Q & A

What is the leading cause of death globally according to the script?

Cardiovascular disease, which includes heart attacks and strokes, is the leading cause of death globally.

What is atherosclerosis and how does it relate to cardiovascular disease?

Atherosclerosis is the technical term for the process where cholesterol gets inside the artery wall and triggers an inflammatory response, leading to a buildup in the artery that can cause heart attacks and strokes.

At what age can signs of atherosclerosis be observed in autopsy studies?

Signs of atherosclerosis can be observed in people in their 20s, as revealed by autopsy studies conducted on individuals who died from unrelated causes.

What is the average age for men to experience a cardiovascular event like a heart attack or stroke?

For the average male, a cardiovascular event like a heart attack or stroke typically occurs around mid-60s.

How does the risk of experiencing a cardiovascular event differ between men and women?

Half of men who will have a heart attack or stroke will experience it before they are 65, while for women, it's a third who will have such an event before they are 65.

What is the speaker's view on the potential for change in one's late 40s regarding cardiovascular health?

The speaker believes that it's not too late to make changes in one's late 40s to improve cardiovascular health.

What is the speaker's perspective on the current approach to healthcare and disease prevention?

The speaker suggests that the current healthcare system is more focused on treating diseases rather than preventing them, and there is a need to shift the focus towards prevention.

What are the two primary tools the speaker mentions were taught during medical school?

The two primary tools taught during medical school, according to the speaker, are procedural tools, such as surgery, and pharmacologic tools, which involve the use of drugs.

Why does the speaker believe there is a lack of precision in the primary tools of prevention?

The speaker believes there is a lack of precision in the primary tools of prevention because medical training does not emphasize understanding nutrition, exercise, sleep, and emotional health, which are crucial for prevention.

What does the speaker propose as a solution for individuals to take control of their health?

The speaker proposes that individuals should take agency over their health by learning and applying knowledge about nutrition, exercise, sleep, and emotional health, which are not typically covered in-depth during medical training.

How does the speaker suggest reallocating healthcare resources to improve both individual health and societal costs?

The speaker suggests reallocating a portion of the healthcare resources spent in the last year or two of a person's life to earlier stages, such as investing in preventive measures like nutrition, exercise, and access to quality foods, which would save money and improve life quality.

💔 Early Onset of Cardiovascular Disease

The paragraph discusses the prevalence of cardiovascular disease, which is the leading cause of death globally for both men and women. It uses the example of atherosclerosis, where cholesterol deposits in artery walls, leading to inflammation and potentially heart attacks or strokes. Autopsy studies reveal that even individuals in their 20s can show signs of this process, indicating it begins early in life. The average male may not experience clinical significance until mid-60s, with 50% of heart attacks or strokes occurring before age 65. For women, it's a third before 65. The speaker emphasizes that it's never too late to address this risk, but there's a common misconception that if one feels fine in their late 40s, they're safe. The paragraph also touches on the need to shift focus from treating diseases to preventing them, criticizing the current healthcare system for not adequately preparing doctors in areas like nutrition, exercise, and emotional health, which are crucial for prevention.

🛠️ Transforming Healthcare Through Individual Empowerment

This paragraph addresses the broader issue of how healthcare systems can be improved to focus more on prevention. The speaker admits a lack of expertise in restructuring healthcare systems but suggests that doctors are often inadequately trained in areas like nutrition, exercise, and emotional health, which are vital for disease prevention. The speaker advocates for a more proactive approach where individuals take control of their health, using their book as a guide for self-improvement in these areas. The paragraph criticizes the current model where a significant portion of healthcare spending occurs in the last year of a person's life, suggesting it would be more effective to invest in preventive measures earlier. The speaker proposes ideas like subsidizing healthy foods and providing better access to quality trainers as ways to make preventive care more affordable and accessible, ultimately saving money and improving life quality.

Keywords

💡Cardiovascular disease

Cardiovascular disease refers to conditions that involve narrowed or blocked blood vessels that can lead to a heart attack, chest pain, or stroke. It is the main theme of the video as it is identified as the number one cause of death globally. The script discusses atherosclerosis, a form of cardiovascular disease, which is the process where cholesterol builds up in the artery walls, starting from a young age and potentially leading to serious health issues later in life.

💡Atherosclerosis

Atherosclerosis is a specific type of cardiovascular disease characterized by the buildup of plaques in the arterial walls. The term is used in the script to illustrate the early onset of cardiovascular issues, as autopsies of young individuals have shown signs of this condition, indicating that the process begins very early in life.

💡Cholesterol

Cholesterol is a waxy substance that is essential for the body's functions but can become problematic when it accumulates in artery walls, as mentioned in the script. High levels of 'bad' cholesterol (LDL) contribute to atherosclerosis, which is a key point in the discussion about the prevention of heart disease.

💡Inflammatory process

In the context of the script, the inflammatory process refers to the body's immune response to cholesterol deposits in artery walls, which can lead to atherosclerosis. This process is part of the body's attempt to heal but ultimately results in further arterial damage, highlighting the complex relationship between the body's natural defenses and disease progression.

💡Heart attack

A heart attack is a serious medical condition that occurs when blood flow to a part of the heart is blocked. The script uses heart attacks as an example of the severe consequences of untreated cardiovascular disease, emphasizing the importance of early prevention and intervention.

💡Stroke

A stroke is another severe consequence of cardiovascular disease, resulting from a blocked or burst blood vessel in the brain. The script mentions stroke as part of the broader discussion on the significance of cardiovascular health and the need for preventive measures.

💡Prevention

Prevention in the script refers to the采取措施 to stop diseases from developing in the first place, rather than treating them after they occur. The speaker argues for a shift in focus from treatment to prevention, suggesting that individuals have the power to take control of their health through lifestyle choices.

💡Nutrition

Nutrition is the process of providing or obtaining the necessary nutrients for health and growth. In the script, nutrition is highlighted as a critical component of preventive health care that medical professionals are often not trained in, underscoring the need for individuals to educate themselves about the impact of diet on health.

💡Exercise

Exercise is a form of physical activity that helps maintain and improve health and fitness. The script emphasizes the importance of understanding and incorporating exercise into daily routines as a means of preventing diseases and improving overall well-being.

💡Sleep

Sleep is the natural, periodic state of rest characterized by a decrease in bodily movement and activity. The script mentions sleep as an essential aspect of health that is often overlooked, suggesting that adequate sleep is crucial for preventing diseases and maintaining health.

💡Emotional health

Emotional health refers to one's overall psychological well-being. The script touches on emotional health as an integral part of a person's health that medical professionals are not typically trained to address, indicating the need for individuals to be proactive about their mental and emotional well-being.

💡Medical infrastructure

Medical infrastructure refers to the systems and resources available in healthcare, including training, facilities, and practices. The script discusses the need to reform medical infrastructure to include more comprehensive training for physicians in areas like nutrition and exercise, which are vital for disease prevention.

💡Healthcare system

The healthcare system encompasses all organizations and resources that provide medical services to people. The script criticizes the current state of healthcare systems worldwide for their focus on treatment rather than prevention, suggesting that systemic changes are necessary to prioritize and support preventive measures.

💡Activation energy

In the script, activation energy is used metaphorically to describe the initial effort required to make significant changes, such as shifting societal and healthcare practices towards prevention. It implies that there is a substantial barrier to overcome in order to initiate these changes, even though they could lead to substantial benefits.

Highlights

It's never too late to address cardiovascular disease, which is the leading cause of death globally.

Atherosclerosis, the buildup of cholesterol in artery walls, can begin as early as in one's 20s.

The body's inflammatory response to cholesterol in arteries can lead to heart attacks and strokes.

Cardiovascular diseases often manifest clinically in men in their mid-60s and women earlier.

The current healthcare system tends to focus on treating diseases rather than preventing them.

Doctors are often not trained in preventive medicine such as nutrition, exercise, and sleep.

There is a lack of precision in preventive healthcare compared to specialized treatments like chemotherapy.

Individuals have the power to take control of their health through self-education and proactive measures.

The author wrote a book to serve as an operating manual for individuals to manage their health independently.

Healthcare spending is often concentrated in the last 12 months of a person's life, which is inefficient.

Investing in preventive measures early in life could save money and improve life quality.

The healthcare system needs a significant shift to prioritize prevention and early intervention.

High-quality trainers and accessible preventive tools like CGMs could be part of a proactive healthcare approach.

Subsidizing healthy foods and making them more accessible could improve public health.

There is a need to overcome the inertia and activation energy in healthcare to implement these changes.

Transcripts

well it's never too late um and it

certainly depends on the condition um

but I'll certainly give you a very

extreme example and then we can

extrapolate from there so we know let's

start let's just talk about

cardiovascular disease because it is

it's like heart attacks and Str heart

attacks and strokes because that's the

number one cause of death globally uh

and it's the number one cause of death

for men and women so uh you know if

you're listening to us talk today

chances are this is your number one risk

factor we know from autopsy study that

are conducted on people in their 20s who

have died for unrelated causes that they

already have signs of atherosclerosis

which is the technical name for what

happens when cholesterol gets inside the

artery wall and an inflammatory process

takes place that ultimately leads to for

example heart attack and this is sort of

the furring up of your artery slowly

over yeah and what's really happening is

the the body is attacking the inside of

the artery where this cholesterol gets

thinking it's a foreign adversary when

in reality it's not but in the process

of doing so it creates more of a problem

than is warranted and you're saying that

when they they've done autopsies to

somebody in their 20s for nothing to do

with um someone who dies in a car

accident car accident you can already

start to see the signs of you can see

evidence that this that this process has

been a decade in the making in other

words this process basically begins at

Birth now for the average person that

process probably won't reach clinical

significance if you're a male until

you're in your mid-60s so 50% of men who

go on to have a heart attack stroke or

die suddenly from one of those two will

have that event take place before the

time they are 65 so for women it's a

third of women who will have a heart

attack stroke or die of heart attack or

stroke will have that occur before they

are 65 so when you ask the question okay

I'm in my late 40s is it too late for me

well I would say no it's not right the

fact that you're sitting here right

tells me it's not too late to do

anything about it um but where a lot of

people get lulled into a false sense of

security is hey I'm in my late 40s and

everything looks pretty good yeah so how

do we change the focus from treating

diseases to preventing people become

becoming sick in the first place and I

guess particularly I think if you're

listening to this is not just an

abstract question but maybe you know for

the individual themselves because I

think generally they will find that if

they go and see their doctor um if

they're not clearly sick with something

then they'll be like oh you're fine you

know go away come back when you're sick

yeah I mean there's two ways to think

about your

question and I think there's one way

that I feel qualified to speak and

there's one way that I don't so I'll

start with the way that I don't if

you're asking the question from a

structural

standpoint how would we fix the Health

Care system and again this doesn't

really matter if you're talking about

the NHS or the US healthcare system or

the Healthcare System anywhere in the

world yeah it's the same everywhere yeah

I would say to do that you have to go

back to the way Physicians are trained

when I was in medical

school I only really learned about two

tools which were procedural tools and

pharmacologic tools procedural tool

means like surgery Sur yeah I mean I

trained as a surgeon so basically you

those were the two things that you

learned You Bic chop something out or

you give someone a drug that's right

those were your tools and again I do not

want to suggest that those are not

valuable tools I do not want to

disparage the remarkable things that

those tools have done again they have

doubled our lifespan in a gener in in

four generations right um I'm simply

pointing out that all the stuff we're

now talking about will require that you

understand nutrition and you understand

exercise and you understand sleep and

you understand emotional health and I

was not trained in any of those things

and I know that my peers were not

trained in any of those things so some

of us have learned those things but we

had to learn them outside Tim always

says that um you know if you're lucky

you get a half day of training on

nutrition in your entire training as a

doctor and probably most of the students

aren't even there for that like half day

on nutrition I mean even if you said

okay going forward you know Physicians

are going to have to spend an entire

semester learning about exercise

nutrition and sleep they would have to

really understand how to apply those

tools I don't think there's any doctor

listening to this or for that matter any

patient listening to this who hasn't

been told by their doctor that they

should sleep that they should eat less

that they should exercise more but

that's relatively unhelpful advice it's

sort of like a patient with cancer being

told by their oncologist that they

should get chemotherapy I mean if the

advice ended there it would be of no

value right yes the reason that you see

the oncologist when you have cancer is

the profound Precision that goes into

which chemotherapy how should it be

dosed based on my body weight based on

my kidney function based on my liver

function how would you monitor for

recurrence how would you modify the

treatment if I'm not responding think of

all the new on that a physician can

provide today within his or her area of

expertise and think about the complete

and utter lack of that nuance and

sophistication that goes into the

primary tools of prevention and I

haven't really answered your question

because all I did was tell you the part

that I don't know how to fix which is

how do you change the medical

infrastructure tell me about the but you

can fix well I think the part that we

can fix is where you started with which

is as the individual we just have that

agency to ourselves that's kind of why I

wrote the book right I wanted to write a

book that could be an operating manual

for the person who acknowledges that

maybe the system isn't perfect but what

can I do to say okay like now I know a

lot of this stuff and I don't need a

physician for it I mean you don't need a

physician to help you fix your nutrition

or your exercise or your sleep or your

emotional health and I think you know

one of the things that um is frustrating

I think is clearly we're spending almost

all of our money on Health Care in this

prevention regime which you know I think

often some extraordinary fraction of

this is spent in the last 12 months of

somebody

life it's sort of got too late to be

able to really

improve very frustrating about this yeah

and in fact even if you didn't care one

iota about a person's life even if you

were simply counting the

beans it would make so much more sense

to take half of that money that is being

spent in the last year or two of a

person's life and spend it in the

earlier part of their life and

again I'm just going to use the NHS as

an example because we're here but

imagine if the NHS said you know what

we're going to slap cgms on everybody

and we're going to pay for it and you

know what we're going to make sure that

there are a lot of really highquality

trainers out there who can work with

people and get them independently

working and exercising and you know what

we're going to fix the system such that

you know it becomes less expensive to

buy high quality foods so that you know

we're kind of subsidizing the right

Foods instead of the wrong foods like I

could go on and

on it you would save money as a society

and improve the quality of an

individual's life it there just has to

be kind of you know an inertia that has

to be overcome to do that there's an

enormous activation energy to make that

happen
