Defining Vitality and Longevity

Dr. Peter Attia discusses his definition of vitality and longevity.

Defining Vitality and Longevity

• Lifespan is binary, you are alive or not alive.

• Longevity involves both lifespan and healthspan.

• Healthspan is the period of time by which an individual remains healthy.

Introduction to Health Span

In this section, the speaker introduces the concept of health span and explains how it is related to physical, cognitive, and emotional health.

Three Dimensions of Health Span

• Health span can be thought of in terms of three dimensions: physical, cognitive, and emotional.

• Physical health refers to lifespan beyond just disability and disease.

• Cognitive health refers to independent function separate from pathology such as dementia.

• Emotional health is the most complicated dimension because there are no biomarkers for it.

Death Bar Analysis

In this section, the speaker discusses the major exit points for people along the lifespan route and introduces the concept of death bar analysis.

Four Horsemen of Death

• The four horsemen of death are largely speaking diseases related to atherosclerosis: cardiovascular disease and cerebrovascular disease.

• Cardiovascular disease is the number one cause of death globally with 18-19 million deaths per year compared to cancer at 11 million deaths per year.

• When cerebrovascular disease is included, it adds a bit more to these numbers.

• Strokes result from an embolic phenomenon as opposed to hemorrhagic phenomenon.

Factors that Predispose People to Bleeding and Clotting

In this section, the speaker discusses factors that can predispose people to bleeding or clotting.

Factors Predisposing People to Bleeding and Clotting

• Certain genetic mutations such as Factor V Leiden can exacerbate clotting in women taking certain oral contraceptives.

• For healthy individuals who want to know if they are predisposed to bleeding or clotting, blood pressure is the most important factor. Hypertension is the leading driver of hemorrhagic stroke phenomenon.

• The more aggressively blood pressure is managed within the 120 over 80 range, the better. Manual blood pressure measurement is better than automated cuffs.

Importance of Blood Pressure Management

In this section, the speaker emphasizes the importance of managing blood pressure for reducing heart attacks and strokes.

Managing Blood Pressure

• Recent studies show that managing blood pressure more aggressively within the 120 over 80 range reduces heart attacks and strokes.

• Blood pressure should be measured correctly by having a person sit still for five minutes before measuring it. Manual cuff measurement is better than automated cuffs.

• Many people have high blood pressure without knowing it because readings taken in doctor's offices can be misleading due to white coat hypertension.

Checking Your Own Blood Pressure

In this section, the speaker explains how people can check their own blood pressure at home.

Checking Your Own Blood Pressure

• It is possible for people to check their own blood pressure manually with a cuff and stethoscope.

• Manual blood pressure measurement is better than automated cuffs, but automated cuffs can still be useful. There can be a 10 to 15 point difference between manual and automated measurements.

• Checking blood pressure at home is not rocket science and can be learned with practice.

Blood Pressure Monitoring

In this section, the speaker discusses the importance of blood pressure monitoring and provides recommendations for how to monitor it.

Importance of Blood Pressure Monitoring

• Blood pressure is important because arteriosclerosis is at the top of the list of risks for dying.

• Manual blood pressure cuffs are considered more accurate than automated ones.

• Automated cuffs tend to run high, and there is no credible explanation from cardiologists as to why.

• People should start with an automated cuff and do two recordings a day for two weeks.

Continuous Blood Pressure Monitoring

• A wrist device that checks blood pressure every 15 minutes throughout the day would be ideal.

• Continuous blood pressure monitoring would be an integral part of a person's health checkup once a year.

• Currently, wearing a blood pressure cuff attached to a clumsy device that goes through the whole insufflation exercise every 15 minutes is cumbersome.

Preventing Arteriosclerosis

In this section, the speaker discusses three major ways to prevent arteriosclerosis.

Three Major Ways to Prevent Arteriosclerosis

1. Maintain good blood pressure (120 over 80 or better).

2. Do not smoke because smoking is devastating from a chemical perspective and completely irritating to the endothelium.

3. Exercise regularly because it helps maintain healthy arteries.

Foundational Piece in Preventing Arteriosclerosis

• The foundational piece in preventing arteriosclerosis is eating a healthy diet that includes nutrient-dense foods such as vegetables, fruits, nuts, seeds, legumes, and whole grains.

Factors that Irritate the Endothelium

In this section, Dr. Peter Attia discusses factors that irritate the endothelium and make individuals susceptible to APO B bearing lipoproteins.

Chemical and Mechanical Irritants

• Chemical irritants such as smoking can cause irritation to the endothelium.

• Mechanical irritants such as high blood pressure can also cause irritation to the endothelium.

Smoking, Cannabis, and Vaping

In this section, Dr. Peter Attia talks about smoking, cannabis, and vaping.

Smoking vs. Vaping

• Smoking cannabis is not better than smoking cigarettes in terms of harm.

• The dose of cannabis seems to be significantly lower than cigarettes.

• Vaping is not a good idea but it's probably significantly less harmful than smoking.

Risks Associated with Smoking

• Smokers are at a higher risk of many cancers including lung cancer and cardiovascular disease.

• A person who smokes a joint a day would be like smoking a cigarette a day which is 20th of a pack.

Risks Associated with Vaping

• The chemical constituents of vape are terrible for people and loaded with carcinogens.

• Many chemicals in vape cross the blood-brain barrier which worries Dr. Attia especially since most experiments are ongoing in young people.

Medical Applications of Cannabis

In this section, Dr. Peter Attia talks about the medical applications of cannabis.

THC to CBD Ratio

• High THC containing cannabis clearly predisposes especially young males to later onset psychosis.

• Pure CBD form is actually quite effective for the treatment of certain forms of epilepsy.

Controversy Around Cannabis

• The discussion around cannabis gets a little contentious for reasons that aren't important.

• Clearly, cannabis has medical applications.

The Importance of Clean Air

In this section, the speaker discusses the importance of being mindful of what we inhale and how it affects our body. He emphasizes that anytime we inhale something, our body absorbs it, and particulate matters in air pollution can have long-term effects on our health.

The Dangers of Air Pollution

• Particulates less than 2.5 microns are getting straight into the body.

• More people are dying from particulate matters in air than CO2 emissions.

• Air pollution disrupts breathing for a long period of time.

• Small particulates can end up embedded in brain tissue for an extremely long period.

Cleaner Energy for Better Health

In this section, the speaker argues that cleaner energy is not just about reducing greenhouse gases but also about improving air quality and preventing deaths caused by air pollution.

Making It Better for People

• Cleaner energy should be about making it better for people to not die from direct consequences.

• By focusing on cleaner energy, we can bypass debates around climate change and get straight to the issue at hand.

Understanding APO B

In this section, the speaker explains what APO B is and why it's important to keep track of its levels in our bodies.

What Is APO B?

• APO B is a protein found in LDL cholesterol particles that transport cholesterol throughout the body.

• High levels of APO B increase risk factors for heart disease and stroke.

• APO B is a better predictor of heart disease risk than LDL cholesterol levels.

Importance of Cholesterol

In this section, the speaker discusses the importance of cholesterol in the body and why it is necessary for survival.

Structural Component of Cell Membranes

• Cholesterol is a crucial structural component of cell membranes.

• Cells are spheres that morph and move, allowing them to be next to each other.

• Channels across cells are held in place by cholesterol and phospholipids.

Precursor to Important Hormones

• Cholesterol is the precursor to some of the most important hormones in our body.

• Sex hormones such as testosterone, estrogen, progesterone, and glucocorticoids are all templates of cholesterol.

Demand Problem

• Not every cell can make as much cholesterol as it needs all the time.

• During sickness or stress, certain cells like adrenal glands need more cortisol production than they can make. They borrow or take cholesterol from other cells in the body.

Water Solubility Problem

• Cholesterol being a lipid is not water-soluble.

• The circulatory system is made up of water plasma which makes it difficult for lipids like cholesterol to move around easily.

• The body designed a vehicle called lipoprotein that was water-soluble on the outside and fat-soluble on the inside.

Understanding APO B and Lipoproteins

In this section, the speaker explains what APO B is and how it relates to lipoproteins. They also discuss the difference between LDL and HDL.

APO B and Lipoproteins

• APO B is a protein that wraps around a subset of lipoproteins.

• There are many apolipoprotein As (APOAs), which are part of the high-density lipoprotein family. The low-density lipoprotein lineage includes LDL, VLDL, and IDL.

• HDL has higher density with more protein and less lipid while LDL has lower density with more lipid to protein.

• ApoBs are atherogenic, meaning they contribute to atherosclerosis.

The Role of LDL in the Body

In this section, the speaker discusses why we have LDL in our bodies and its functional role.

Functional Role of LDL

• LDL helps shuttle cholesterol to tissues that need it like adrenals, muscle, heart etc.

• There is no evidence that having high levels of LDL reflects healthy metabolic needs.

• Most species do not have apob or LDL in their bodies.

Cholesterol's Role in Brain Health

In this section, the speaker talks about cholesterol's role in brain health.

Cholesterol's Role in Brain Health

• Cholesterol is critical for synaptogenesis process which forms connections between neurons during brain development.

Cholesterol and CNS Development

In this section, the speaker discusses the relationship between cholesterol and CNS development in infants and children.

Importance of Cholesterol in CNS Development

• Infants and children have low levels of cholesterol, which is important for CNS development.

• Despite low levels of serum cholesterol, infants and children undergo CNS maturation without any problems.

Total Body Pool of Cholesterol

• The circulatory pool of cholesterol represents only a fraction of the total body pool.

• Serum cholesterol levels rise monotonically throughout life.

APO B vs LDL-C

• APO B refers to the lipoprotein wrapped around an LDL particle.

• APO B level is a direct measurement of the concentration of LDL particles and is more predictive of risk than LDL-C.

Red Flag Cut Off for APO B Level

• The high-end flag for APO B level depends on various factors such as age, sex, family history, etc.

• It's important to consider individual objectives when interpreting APO B level.

APO B and Causality

In this section, the speakers discuss the importance of causality in medicine and how it relates to APO B and atherosclerosis.

Smoking and Lung Cancer

• Smoking is causally related to lung cancer.

• Causality is an obsession of one speaker because it's difficult to infer causality for most things in medicine.

• If smoking cessation reduces the probability of lung cancer, then logically, smoking causes lung cancer.

APO B and Atherosclerosis

• There is no ambiguity that APO B is causally related to atherosclerosis.

• Mendelian randomization shows that there is a gradation of LDL concentration or apob concentration that occurs from insanely low to insanely high.

• Medicine today is backward because we're doing 10-year risk calculations instead of focusing on preventing people from crossing the threshold where their risk of disease becomes high.

Understanding Cardiovascular Risk Factors

In this section, the speaker discusses how doctors determine a person's risk for adverse cardiac events and why it is important to treat causal and modifiable risk factors.

Determining Cardiovascular Risk

• Doctors use various factors such as blood pressure, smoking history, family history, and age to determine a person's risk for adverse cardiac events.

• The models used to calculate cardiovascular risk do not work if a person is below 40 years old.

Treating Modifiable Risk Factors

• Even if a person's calculated risk is less than 5%, it is still important to treat causal and modifiable risk factors such as LDL or apob.

• The earlier treatment starts, the less aggressive it needs to be. If there are no other risk factors present and no evidence of damage on CT angiograms, treating apob at the fifth percentile of the population (about 60 milligrams per deciliter) may be sufficient. However, if there are other risk factors present or evidence of disease on CT angiograms, treating apob at 30 to 40 milligrams per deciliter may be necessary.

Importance of Causality in Assessing Risk

• Just because something is causal does not mean that a person will definitely experience adverse effects from it. For example, some smokers do not get lung cancer. Therefore, assessing an individual's cardiovascular risk requires making judgments based on heterogeneous population data and distinguishing between causal and non-causal inferences around risk.

Lowering APO B Levels

In this section, the speaker discusses how nutrition can help lower APO B levels and when pharmacotherapy may be necessary.

Lowering APO B with Nutrition

• Fixing insulin resistance in an insulin-resistant person can help lower APO B levels. Elevated triglycerides are a hallmark of insulin resistance.

Pharmacotherapy for Lowering APO B

• Once APO B levels need to be lowered to the 30 to 60 range, pharmacotherapy may be necessary. The most common forms of prescription medication include statins, PCSK9 inhibitors, and ezetimibe.

• Statins are the most commonly used medication for lowering cholesterol and have been shown to reduce the risk of adverse cardiac events. However, they can have side effects such as muscle pain and weakness. PCSK9 inhibitors and ezetimibe are newer medications that can also lower cholesterol but are more expensive than statins.

Fixing Insulin Resistance and Lowering Triglycerides

In this section, the speaker discusses how to fix insulin resistance and lower triglycerides.

Normal Range for Triglycerides

• Most laboratory tests consider normal to be up to 150 milligrams per deciliter.

• Ideally, trigs should be at or below HDL cholesterol.

Carbohydrate Restriction for Lowering Triglycerides

• Carbohydrate restriction is the most effective way to lower triglycerides.

• Even under eucaloric conditions, carbohydrate restriction will lower triglycerides.

• Energy restriction would be the first order of business, but within that, carbohydrate restriction will probably get you there quicker.

Exercise for Improving Lipids

• Exercise can improve lipids in general, especially combinations of resistance training and cardiovascular exercise.

Pharmacotherapy for Cholesterol Control

In this section, the speaker discusses pharmacotherapy options for controlling cholesterol levels.

Statins

• Statins work by targeting an enzyme called HMG-CoA reductase that is very high in the synthetic pathway of cholesterol production.

• The liver senses a reduction in the body's pool of cholesterol and increases its expression of LDL receptors. This leads to more apob particles coming out of circulation.

Acetamide

• Acetamide works by blocking the Neiman pick C1 like one transporter in the enterocyte responsible for absorption of cholesterol.

• The ATP binding cassette G5 G8 spits excess cholesterol out, but in a lot of people, it doesn't work very well and can't properly regulate the total body pool of cholesterol.

• Acetamide has virtually no side effects. It's not unheard of to see an elevation in liver enzymes when zetamide is combined with a statin.

Statins and PCSK9 Inhibitors

This section discusses the side effects of statins and the benefits of PCSK9 inhibitors.

Side Effects of Statins

• Statins have side effects, including muscle soreness in 5% of people and brain fog in a narrower subset.

• Insulin resistance is another potential side effect that can be detected through periodic CGM tracking.

• However, there are many statin options available now, with at least two having a low side effect profile.

Benefits of PCSK9 Inhibitors

• Familial hypercholesterolemia (FH) is a genetic condition that causes very high cholesterol levels and a high incidence of atherosclerosis.

• PCSK9 inhibitors were developed based on the discovery of mutations in the pcsk9 gene that either degrade or don't affect LDL receptors. These inhibitors can help manage FH by reducing LDL cholesterol levels.

Short-term Benefits of Circulation

In this section, the speaker discusses whether there are any short-term benefits to improving circulation and reducing APO B levels.

Positive Side Effects of Reducing APO B Levels

• The speaker explains that there are no immediate positive side effects when taking drugs to reduce APO B levels.

• However, it is important to intervene early because atherosclerosis can be asymptomatic and the most common presentation of a heart attack is death.

• The best predictor of a heart attack is still a heart attack, so it's important to measure APO B levels early in life, especially if there is a family history of concern.

Personal Experience with Measuring APO B Levels

• The speaker recommends measuring APO B levels starting in one's 20s or 30s, especially if there is a family history of concern.

• The speaker had his first calcium scan at age 35 and had to convince doctors to perform the test due to his young age. He believes he should have measured his APO B levels earlier in life.

Inside Tracker

The benefits of using Inside Tracker for personalized nutrition and how it can help you reach your health goals.

Personalized Nutrition Platform

• Inside Tracker is a personalized nutrition platform that analyzes data from your blood and DNA to help you better understand your body.

• Blood work is the only way to monitor markers such as hormone markers, lipids, metabolic factors, etc. that impact immediate and long-term health.

• With Inside Tracker, changing values becomes straightforward because it has a personalized dashboard that addresses nutrition-based behavior-based supplement-based approaches.

APO Lipoprotein B

• Inside Tracker now includes a measurement of APO lipoprotein B (APOB), which is a key marker of cardiovascular health.

• There's extreme value in knowing your apob levels.

Adjusting Blood Pressure

How to adjust blood pressure without medication.

Weight Management and Exercise

• Weight management is crucial in adjusting blood pressure.

• Exercise every day helps lower blood pressure.

• Three to four hours per week of zone two exercise is recommended.

Medication

• If all fixable stuff has been fixed and an individual still has high blood pressure, medication may be necessary.

Importance of Kidney Health

The importance of kidney health in living longer.

Glomerular Filtration Rate

• Once the glomerular filtration rate falls below a certain level, one has to be very careful with how they live their life.

• It's important to start thinking about the capacity of the kidney when trying to live longer.

The Importance of Kidney Function

In this section, the speaker discusses the importance of maintaining good kidney function and how it can impact overall health.

The Hazards of Compromised Kidney Function

• A person with compromised kidney function is at risk for needing dialysis in the future.

• All-cause mortality associated with compromised kidney function is greater than that of heart disease.

• End-stage renal disease has a higher risk of death than cancer.

Avoiding Arthrosclerosis and Cancer

In this section, the speaker talks about ways to avoid arthrosclerosis and cancer.

Sensitivity of Kidneys to Blood Pressure

• The kidneys are sensitive to blood pressure due to their small size and proximity to the heart.

Alcohol Consumption and Cancer Risk

• There is no dose of ethanol that is healthy for consumption.

• One drink per day may not have measurable harm for most people, but beyond that, the risk starts to climb steeply.

• It's difficult to discern harm from up to one drink per day, but it's important not to consume seven drinks in one day or disrupt sleep patterns.

Emerging Literature on Alcohol Consumption

In this section, the speaker discusses emerging literature on alcohol consumption.

Emerging Literature on Alcohol Consumption

• Emerging literature suggests that more conservative folks are starting to place limits on alcohol consumption.

Drinking Philosophy

In this section, the speaker talks about his drinking philosophy and how he approaches alcohol consumption.

Drinking Philosophy

• The speaker drinks occasionally but can go weeks without having a drink.

• He only drinks good quality alcohol that he enjoys and will not drink bad alcohol even if it is expensive.

• Although he has consumed alcohol in the past, he does not enjoy the taste or experience of it.

• The speaker believes that longevity is also about health span and part of health span is quality of life. Therefore, he thinks that one should make trade-offs when it comes to consuming things they enjoy.

Alcohol and Health

In this section, the speaker discusses the impact of alcohol on cardiovascular disease, cerebrovascular disease, sleep, and neurodegenerative diseases.

Impact of Alcohol on Health

• Alcohol cannot be directly linked to cardiovascular disease and cerebrovascular disease but may have indirect effects through insulin by altering insulin sensitivity.

• The impact of ethanol on sleep is underappreciated but can have a profound effect on cardiovascular cerebrovascular disease.

• Neurodegenerative diseases are heavily impacted by ethanol consumption.

Balancing Enjoyment with Health

In this section, the speaker talks about balancing enjoyment with health when it comes to consuming things like alcohol.

Balancing Enjoyment with Health

• The speaker enjoys consuming certain types of alcohol but knows that if he has too much, his sleep will suffer. Therefore, he rarely crosses his threshold of alcohol consumption.

• The speaker believes that if optimizing every molecule of one's being deteriorates the quality of life, then what is the point? Therefore, he thinks that one should make trade-offs when it comes to consuming things they enjoy.

• The speaker believes that longevity is also about health span and part of health span is quality of life. Therefore, he thinks that one should make trade-offs when it comes to consuming things they enjoy.

Reducing Risk of Cancer

In this section, the speaker talks about reducing the risk of cancer.

Reducing Risk of Cancer

• The speaker mentions that nobody wants cancer and provides statistics on cancer rates.

• No further bullet points are available for this section.

Prostate Cancer and Cancer Categories

In this section, the speaker discusses prostate cancer and how it differs from other types of cancers. They also explain the role that genes play in cancer development.

Prostate Cancer and Other Cancers

• About one in six men will die from prostate cancer.

• Prostate cancer is easy to screen for and treat when caught early.

• Breast cancer, pancreatic cancer, and glioblastoma are more complicated than prostate or colon cancers.

• Each type of breast cancer is different from the others, making them unique diseases.

The Role of Genes in Cancer Development

• Less than 5% of cancers result from germline mutations inherited from parents.

• Mutations in genes like BRCA are germline mutations that drive cancer development.

• Over 95% of cancers arise from somatic mutations acquired during a person's lifetime.

• Smoking and obesity are two environmental factors that can cause somatic mutations.

Obesity as a Driver of Cancer

In this section, the speaker explains how obesity can lead to an increased risk of developing certain types of cancers.

Understanding Obesity as a Proxy

• Obesity is now the second most prevalent environmental driver of cancer after smoking.

• BMI is not a perfect proxy for measuring obesity since it doesn't take into account lean muscle mass versus fat mass.

• Waist-to-height ratio may be a better metric for measuring obesity.

• A waist circumference greater than 50% of a person's height is cause for concern.

The Link Between Obesity and Cancer

• Obesity can lead to chronic inflammation, which can increase the risk of cancer.

• Fat cells produce hormones that can promote cancer growth.

• Obesity is linked to an increased risk of developing breast, colon, pancreatic, and other types of cancers.

The Physiology of Cancer

In this section, the speaker discusses the physiology of cancer and its relationship with obesity.

Obesity and Cancer

• Obesity is not a direct cause of cancer.

• Insulin resistance and inflammation are two factors that come with obesity that can lead to cancer.

• Certain environmental toxins also increase the risk of cancer.

Alcohol and Cancer

• Alcohol is a carcinogen, but it's unclear how much alcohol consumption increases the risk of cancer.

• Genetic predispositions may play a role in determining an individual's susceptibility to alcohol-related cancers.

Screening for Cancer

In this section, the speaker discusses the importance of screening for cancer.

Importance of Screening

• Screening is important because there is no example of a cancer that is more effectively treated when the burden of cancer cells in the body is higher than when it is lower.

• Colon and breast cancers are examples where early detection through screening can significantly improve survival rates.

Whole Body Screens

• Whole body screens for tumors are possible using MRI technology, except for brain tumors which require different methods.

• The speaker argues that screening at an individual level can be beneficial despite traditional medicine's stance against it.

Cancer Screening and Radiation Exposure

In this section, Dr. Rhonda Patrick discusses cancer screening and radiation exposure.

Types of Cancer Screening

• Skin, esophageal, gastric, colon cancers can be directly observed.

• For other cancers inside the body, imaging modalities are used.

• Liquid biopsies are being developed to detect cell-free DNA for cancer detection.

Imaging Modalities for Cancer Detection

• MRI scanners are preferred as they do not use radiation.

• CT scans expose patients to high levels of radiation (30-50 millisieverts).

• Whole-body CT scans should be avoided due to the high levels of radiation exposure.

Sources of Radiation Exposure

• Medical professionals using CT and PET scanners are the biggest culprits.

• Dental x-rays and fluoroscopy also expose patients to low levels of radiation.

• Flying on airplanes exposes passengers to minimal amounts of radiation.

Managing Radiation Exposure

• Patients should choose medical facilities that use faster CT scanners with better software and engineering to reduce radiation exposure.

• Doctors should limit the number of scans a patient receives.

Radiation Exposure and Cancer Risk

In this section, the speaker discusses radiation exposure and cancer risk. He talks about the maximum amount of radiation one should be exposed to in a year, the risks associated with different types of radiation exposure, and how to make good choices to reduce one's risk.

Maximum Radiation Exposure

• The maximum amount of radiation one should be exposed to in a year is 50.

• There are some situations where people may need to exceed this limit, such as cancer treatment.

• However, it is important to be aware of sources of radiation exposure and make good choices to reduce overall risk.

Types of Radiation Exposure

• MRI scanners are preferred because they do not use radiation.

• The speaker has been exposed to mutagens such as formaldehyde and radioactive Proline in specialized circumstances.

• Most people will be exposed to pesticides, paint thinners, and other solvents that can increase cancer risk.

Ubiquity of Carcinogens

• It is difficult to calculate the average cancer risk from everyday exposure to carcinogens.

• Asbestos is ubiquitous in California buildings but may not pose a significant risk unless agitated.

• Micro-pollution from events like 9/11 can also increase cancer risk.

Focus on Controllable Factors

• Rather than worrying about uncontrollable factors like genes or environmental ubiquity, focus on controlling screening frequency and timing.

Genetic Screening and Cancer Screening

In this section, the speaker discusses genetic screening for certain diseases like Alzheimer's disease and cancer screening in some patients. They also talk about the importance of colonoscopy screening for colon cancer.

Genetic Screening

• Sequencing is available now in a variety of formats.

• The speaker's research team is working on deciding which genetic screenings to use.

• They do genetic screening for certain things like apoe, a gene that plays a role in neurodegenerative disease.

• In their practice, they are generally so aggressive with everyone regardless of family history that it turns out to be a little bit moot.

Cancer Screening

• They selectively use cancer screening in some patients but it's less important because they're generally so aggressive anyway.

• Colonoscopy screening for colon cancer was not covered until you were 50. That has been bumped to 45. However, they still think everybody should be screened no later than 40.

• Colon cancer is not just the third leading cause of cancer death; it's 100% preventable because every colon cancer comes from a polyp and every polyp can be seen on a colonoscopy.

Specificity Problem with Aggressive Screening Posture

In this section, the speaker talks about the specificity problem when stacking more modalities around these things. They also discuss MRI as an example.

Specificity Problem

• The biggest challenge with aggressive screening posture is the specificity problem.

• When you stack more and more modalities around these things, you're going to start finding things that aren't cancer.

MRI Example

• MRI has a very high sensitivity which means if a cancer is present an MRI is very likely to see it.

• However, it has a very low specificity which means it will see a bunch of things and think they are cancer when they are not.

• MRI is most troubled by glandular tissue, which is its Achilles heel.

Whole Body MRI for Cancer Screening

In this section, the speaker talks about Whole Body MRI for cancer screening. They also discuss the typical cost of a whole body MRI and how to get one.

Whole Body MRI

• They use Whole Body MRI for cancer screening.

• They tell their patients going in that there's a 25% chance they're going to find something that is not cancer but will require further investigation.

Cost and Availability

• The speaker doesn't know the typical cost because they don't know how many different places are doing it.

• The company that makes the MRI that they're using right now is called Pronuvo.

Introduction

In this section, the speaker introduces himself and talks about his affiliation with a company that does all sorts of diagnostics. He also mentions a prenuvo scanner.

Speaker's Affiliation

• The speaker is affiliated with a company that does all sorts of diagnostics.

• Among them is a prenuvo scanner.

Ways to Offset Cancer and Alzheimer's Disease

In this section, the speaker discusses ways to offset cancer and Alzheimer's disease. He talks about age being the major risk factor for these diseases.

Risk Factors for Cancer and Alzheimer's Disease

• Age is the major risk factor for cancer, Alzheimer's disease, glaucoma disease, cardiovascular disease.

• Everyone experiences some age-related cognitive decline as they get older.

• Slope of cognitive decline can be controlled to some extent.

• Alzheimer's dementia represents just a steep acceleration downward of cognitive decline.

Prevalence of Alzheimer's Disease

• Alzheimer's disease is both the most prevalent form of dementia and neurodegenerative disease in the US.

• Roughly six million people in the United States have Alzheimer's disease.

• The greatest risk factor for getting glaucoma, cardiovascular disease, cancer, or any other neurodegenerative diseases is age.

Neurodegenerative Diseases

In this section, the speaker talks about neurodegenerative diseases such as Lewy Body dementia and Parkinson's disease. He also discusses how age is not modifiable but reducing risks as we age can help reduce our chances of developing these diseases.

Types of Neurodegenerative Diseases

• Lewy Body dementia is a dementing disease but it also has a movement component between Alzheimer's disease and Parkinson's disease on the spectrum.

• Parkinson’s disease is the second most prevalent neurodegenerative disease.

• The rate of growth of Parkinson's disease is the highest.

• There are a lot of other neurodegenerative diseases like multiple sclerosis, ALS, Huntington disease.

Reducing Risks

• Age is not modifiable but reducing risks as we age can help reduce our chances of developing these diseases.

Isoforms of Apolipoprotein E

In this section, the speaker discusses the different isoforms of apolipoprotein E and their historical significance.

Different Isoforms of Apolipoprotein E

• There are three isoforms of apolipoprotein E: E2, E3, and E4.

• The E4 isoform is the oldest and has been present historically. It offered protection against parasitic infections in the CNS.

• The E3 isoform showed up 50,000 years ago while the E2 isoform appeared only 10,000 years ago.

Stratification of Risk for Alzheimer's Disease

• There is a clear stratification of risk for Alzheimer's disease that tracks with these isoforms.

• Double three (E3/E3) is the most common combination at around 55% of the population.

• Three/four (E3/E4) is about 25% of the population.

• Two/two (E2/E2) is less than one percent while four/four (E4/E4) is about one to two percent.

Deterministic Genes in Alzheimer's Disease

• There are at least three deterministic genes in Alzheimer's disease: psen1, psen2, and app.

• These genes collectively make up about one percent of cases of people with Alzheimer's disease.

• If you have those genes, you will get Alzheimer's disease.

The Importance of Amyloid in Alzheimer's Disease

In this section, the speaker discusses the role of amyloid beta in Alzheimer's disease and how it has been overemphasized in research.

Amyloid Beta and Alzheimer's Disease

• Amyloid beta is responsible for the changes seen in the brain with Alzheimer's disease.

• However, there are healthy people who have died with no cognitive impairment but are chock full of amyloid plaques.

• It is not fully understood what removing amyloid does or how important it really is.

• There have been many drugs that target amyloid but have seemed unsuccessful.

App Mutation and Risk for Alzheimer's

• People with the app mutation have one extra cleavage site which results in one extra cleavage of amyloid.

• Misfolding occurs which creates a plaque and predisposes them to neurofibrillary tangles.

• Early papers on amyloid were falsified, setting back research by a decade.

Crisis in the Field

• The field is probably in a bit of a crisis because there have been so many bets placed on anti-amyloid therapies and biomarkers without seeing efficacy.

• Unlike cardiovascular disease where there are biomarkers and clinical outcomes, we don't have any of that for Alzheimer's disease.

Brain Health

In this section, the speaker discusses four things that are unequivocally true for brain health.

Four Unequivocally True Things for Brain Health

• Sleep matters.

• Lower LDL cholesterol and apob is better than higher.

• Not having type 2 diabetes matters to being insulin sensitive.

• Exercise matters. One hour of low-intensity cardio, one hour of strength training, and one hour of interval training per week is the highest use case if you could only exercise three hours a week.

Head Injuries

• Don't hit your head. It seems almost assuredly true in a susceptible individual.

• The best thing to do if you get a head injury is to not get another one by stopping the activity that leads to more head injury.

• The use of hyperbaric oxygen immediately following a TBI (traumatic brain injury) is emerging but needs rigorous study.

Hyperbaric Oxygen and Brain Health

In this section, the speaker discusses hyperbaric oxygen therapy and its potential benefits for brain health. He also mentions other interventions that may be helpful for brain health.

Hyperbaric Oxygen Therapy

• Hyperbaric oxygen therapy is a treatment that involves breathing pure oxygen in a pressurized chamber.

• It can be beneficial for wound healing and concussion treatment.

• The protocols have to be precise, and it's not something to try at home.

• The TBI protocol commonly used is five 60-minute sessions per week at two atmospheres.

• From a cost and time perspective, it's enormous.

Other Interventions for Brain Health

• There are many supplements that could help with brain health, such as curcumin, magnesium with L3 and 8 transporter, methylated vitamins that lower homocysteine, EPA, and DHA.

• Evidence is unimpressive for most of these interventions except exercise, sleep, insulin sensitivity, lipid management.

Accidental Deaths

In this section, the speaker talks about accidental deaths. He separates them into two categories: Automotive accidents/falls/overdoses and other types of accidental deaths.

Automotive Accidents/Falls/Overdoses

• Car accidents are pretty constant throughout life but more common if you're under 60 than over 60.

• Fentanyl-related deaths have basically squashed all other deaths below 65 on the accidental front because of the number of different substances that fentanyl is being woven into everything.

Understanding the Fentanyl Epidemic

In this section, Dr. Jordan Peterson discusses the rise of accidental overdoses, suicides, and alcohol-related deaths in America. He also talks about how fentanyl is causing a significant increase in these numbers.

Rise of Accidental Overdoses

• The number of accidental overdoses has been increasing at almost 20% per year since 2019.

• In 2021, there were about 210,000 Americans who died from accidental overdoses.

• This increase is driven almost entirely by fentanyl use.

Fentanyl Use and Cocaine Users

• People are dying of fentanyl overdose after going out to buy cocaine.

• The majority of people dying from fentanyl poisoning are those using illicit drugs like cocaine.

• Fentanyl is being used because it's cheap and easy to obtain.

Illicit Counterfeit Pills

• Illicit counterfeit pills are the main source of accidental poisonings caused by fentanyl.

• Kids are buying sleeping pills, Adderall, and other counterfeit drugs that are being laced with fentanyl.

• Opioids, barbiturates, sedatives - any drug that can be counterfeited - can be laced with fentanyl.

Protecting Children from Fentanyl Poisoning

• Parents need to warn their children about the dangers of taking any medication without a prescription or medical supervision.

• Parents should tell their children not to trust anyone who offers them medication or drugs, even if they seem trustworthy.

Fentanyl Overdose

In this section, the speakers discuss the dangers of fentanyl overdose and how it can lead to respiratory inhibition.

Dangers of Fentanyl Overdose

• A hundred milligrams of fentanyl is a hit for most people.

• Respiratory inhibition is the primary cause of death from fentanyl overdose.

• Adults and kids are dying from accidental fentanyl overdoses, even those who are not drug addicts.

Accidental Deaths in Aging Population

In this section, the speakers discuss accidental deaths in the aging population and how falls are a significant risk factor.

Falls as a Risk Factor

• Falls are the primary cause of accidental deaths in the aging population.

• The probability of death within 12 months after breaking a femur or hip is high for those over 65 years old.

• The probability of death within 12 months after falling and hitting your head is also high for those over 65 years old.

Preventing Falls

• People's ability to jump and land correlates with their ability to control falls.

• Atrophy of type 2 muscle fibers is the hallmark of aging on muscles.

• Strength training that stresses type 2 fibers, reactivity training, explosive training, jumping and landing exercises can help delay or minimize atrophy.

Eccentric Strength Training

In this section, the speakers discuss eccentric strength training as one pillar of strength training.

Eccentric Strength Training

• Eccentric strength training is one of the pillars of strength training.

• Stepping off something is more likely to cause injury than stepping onto something.

Importance of Physical Fitness for Longevity

In this section, the speaker discusses the importance of physical fitness in maintaining longevity and quality of life as we age. He shares personal anecdotes about his mother's fall and emphasizes the need to focus on what ruins our quality of life rather than just what kills us.

The Four Pillars of Longevity through Physical Fitness

• The four pillars are strength, stability, aerobic efficiency, and aerobic peak output.

• A wide base and a high peak are necessary to maximize the area of the triangle.

• Stability is often overlooked but is crucial for aging well.

• Most machines in commercial gyms do not tap into stability training.

Importance of Stability Training

• Many falls occur when older people cannot slow themselves down while walking downhill or stepping off a curb.

• Broad jumps can be used as a test for explosive movement and landing ability.

• Difficulty recovering from injuries due to immobility and muscle loss can lead to a decline in mobility and quality of life.

• Stability training is important for aging well but often neglected because it is difficult to train.

Conclusion

Physical fitness plays an essential role in maintaining longevity and quality of life as we age. The four pillars of longevity through physical fitness include strength, stability, aerobic efficiency, and aerobic peak output. Stability training is often overlooked but crucial for aging well.

Stability and Emotional Health

In this section, the speaker discusses stability and emotional health. He explains that stability is multi-faceted and involves doing a lot of things. The speaker also talks about how emotional health is potentially the most important aspect of quality of life.

Stability

• Movements in odd planes require stability.

• Deadlift requires an unbelievable capacity to harness intra-abdominal pressure and to be connected.

• Stability involves doing a lot of things, such as step-ups with ipsilateral loads contralateral loads.

Emotional Health

• Emotional health is potentially the most important aspect of quality of life.

• The chapter on emotional health comes across more as a patient's experience rather than expertise.

• Without emotional health, none of the other aspects matter.

Emotional Health

In this section, the speaker discusses emotional health and how it is difficult to define. He mentions that emotional health is made up of several components such as connectivity with others, having a sense of purpose, regulating emotions, experiencing fulfillment and satisfaction.

Defining Emotional Health

• Emotional health is difficult to define.

• It includes connectivity with others, having a sense of purpose, regulating emotions, experiencing fulfillment and satisfaction.

• Being present is an important component of emotional health.

• Presence to what one is doing was found to be a stronger predictor of happiness than anything else.

Challenges in Managing Emotional Health

• Emotional health is the hardest for the speaker to manage.

• Many people have deficits in areas such as being present or maintaining healthy relationships.

• The speaker has difficulty being present and often thinks about the future instead of enjoying the moment.

Importance of Emotional Health

• Emotional health is at the top of the speaker's list when evaluating his own health factors.

• Poor emotional health can create significant pain in one's life.

Being Present and Perception of Time

In this section, Tim Ferriss and Naval Ravikant discuss the challenges of being present in the moment and how our perception of time can affect our ability to enjoy meaningful experiences.

Challenges with Being Present

• Playing with kids requires being present in their world.

• Mind tends to wander when playing with kids.

• Need to savor every moment as they are finite.

Perception of Time

• Our ability to contract and dilate our time perception is remarkable.

• Ability to occupy different timings is a double-edged sword.

• Contemplating mortality may help us be more at peace.

Agency over Life Quality

• We have limited agency over the length of our life but greater agency over quality.

Living for Resume or Eulogy Virtues

In this section, Tim Ferriss discusses the concept of living for resume virtues versus eulogy virtues. He talks about how he was introduced to this idea by David Brooks' book "The Road to Character."

Living for Resume or Eulogy Virtues

• Tim Ferriss discusses the concept of living for resume virtues versus eulogy virtues.

• He recommends David Brooks' book "The Road to Character" as an important read.

• Ferriss talks about the challenge of balancing work and other expectations with emotional well-being and health in relationships.

Enforcing Emotional Well-being

In this section, Tim Ferriss talks about his practices for enforcing emotional well-being and health in relationships.

Practices for Enforcing Emotional Well-being

• Ferriss discusses his past experiences with rehab facilities and highly regimented daily behaviors.

• He compares his interactions with people now versus five years ago, noting that while there are still negative interactions, they are less severe and he makes amends more quickly.

• Ferriss emphasizes the importance of repairing damage when causing it rather than striving for perfection in all areas of life.

Repairing Relationships

In this section, the speaker discusses his approach to repairing relationships and how it differs depending on the nature of the relationship and what is being optimized for.

Repairing Relationships

• When repairing a relationship, it's important to understand what you're optimizing for. Is it the outcome or the relationship itself?

• If it's a transactional interaction, such as buying a car from a stranger, then optimizing for the outcome is more important than the relationship.

• However, if it's someone you care about in a personal or professional context, then both the outcome and the relationship matter.

• Before approaching someone to repair a relationship fracture, take time to fully understand yourself and your own feelings about the situation.

• This may involve seeking guidance from a therapist or trusted friend.

• It's important to consider whether repairing the relationship is worth pursuing based on its nature and importance.

Overall, repairing relationships requires careful consideration of what is being optimized for and an understanding of oneself before approaching others.

Understanding Emotions

In this section, the speaker talks about how anger is often a response that is superimposed on top of other emotions such as hurt, fear, or shame. They discuss the importance of being able to deconstruct what one is feeling in order to approach others and communicate effectively.

Deconstructing Emotions

• Anger is often a response that is superimposed on top of other emotions such as hurt, fear, or shame.

• It's important to deconstruct what one is feeling in order to approach others and communicate effectively.

• Sometimes it takes time to figure out what one is really feeling.

• Our ability to know what we're really feeling can be terrible due to the coarseness of language when it comes to describing emotions.

Self-Healing Journey

In this section, the speaker talks about their experience going on self-healing retreats after hitting rock bottom moments in their life. They discuss how difficult these experiences were but also how they helped them understand themselves better.

Going on Retreats

• The speaker went on self-healing retreats after hitting rock bottom moments in their life.

• The process of understanding oneself better can be nuanced and take time.

• The first retreat was recommended by a friend who told the speaker they needed to do it.

• The second retreat was not something the speaker wanted to do but felt like they had no choice due to circumstances.

Childhood Trauma and Emotional Acceptance

In this section, the speaker talks about how childhood trauma can lead to rationalization and emotional detachment. He shares his personal experience of finally accepting his emotions and understanding the implications of childhood trauma.

Emotional Acceptance

• The speaker shares that he had a moment where he dropped his rationalizations and allowed himself to experience what a child would experience in that moment.

• This emotional acceptance helped him understand the implications of childhood trauma on a child's life.

• The speaker emphasizes that accepting emotions does not make one a victim but allows them to let go of adaptations that came from their past experiences.

• The brain repurposes circuitry used as children as adults, making it essential to revisit past traumas from an emotional standpoint.

Practicing Skills

• The speaker uses dialectical behavioral therapy regularly but doesn't have to revisit his childhood often.

• He has learned lessons from revisiting past traumas emotionally and now focuses on practicing skills he has learned.

Managing Anger Through Inner Monologue

In this section, the speaker talks about how he managed his anger through boxing but didn't realize the impact of his inner monologue.

Managing Anger

• The speaker shares that he had an insane amount of anger and rage since childhood.

• Boxing was an outlet for him to exercise six hours a day, which kept him out of jail.

• His inner monologue was filled with hatred towards himself, which contributed to his rage.

• The speaker emphasizes the importance of understanding one's inner monologue and how it impacts their emotions.

Overcoming Negative Self-Talk

In this section, the speaker talks about his experience with negative self-talk and how he overcame it.

Bobby Knight in My Head

• The speaker describes his negative self-talk as being the angriest and most violent self-talk imaginable.

• He explains that this negative self-talk spilled into how he interacted with others, making him an insufferable person to be around.

• The speaker's therapist proposed an exercise where every time he engaged in negative self-talk, he would stop himself and pretend that it was one of his closest friends who made the mistake instead. He would then speak to that person kindly and record it on his phone.

• The speaker sent these recordings to his therapist, which helped him shed his negative self-talk in just four months.

Communicating with Myself Kindly

• The speaker notes that while he still holds himself to a high standard, he is no longer beating himself up like before. By extension, he is also beating other people up less.

• He credits neuroplasticity for allowing him to overcome his negative self-talk at 47 years old.
