In a world where every second counts, where dreams are chased and memories are made, there’s one quest that unites us all…

The quest to live longer and healthier.

“Outlive” is a compelling exploration of the science and strategies behind extending human lifespan and enhancing quality of life.

Drawing on cutting-edge research and real-life anecdotes, the book delves into the mechanisms of aging and the factors that influence longevity, from genetics and lifestyle choices to environmental influences and technological advancements.

In this video, we are going to discuss the best lessons from it.

Alrighty, so without further ado, let’s get started.

Lesson #1: The current healthcare system isn’t really helping you live longer; it’s only delaying the inevitable.

The current approach to medicine and healthcare is that we focus on treating the disease when it starts showing some symptoms.

Most people don’t take chronic diseases seriously until they can’t ignore them—that’s when the diseases start giving them troubles in their daily lives.

The problem is that once you get certain chronic diseases, like diabetes, your longevity is badly affected.

People in general don’t live their lives with the goal of improving their lifespan or healthspan. They just keep on living their lives cluelessly and do nothing to avoid the human suffering that happens because of diseases that generally come after the age of 40.

Also, the current healthcare system isn’t really focused on teaching people how to avoid chronic diseases.

Lifespan and Healthspan are two different things.

Lifespan is the time you will live on this planet.

While Healthspan means how long you will stay healthy.

Health starts declining after you catch a chronic disease.

You can live a decade extra, but if you are not healthy enough, it’s only going to be a pain in the behind.

We should not just try to live longer but also be healthier.

The reason healthcare system isn’t much concerned with improving healthspan is because there is no profit in doing that.

If people start eating healthy, fewer people will get sick, and even fewer will visit clinics.

The smart approach is to just live in such a way that we don’t get the diseases in the first place.

Why not prevent the chronic diseases before they even show their faces?

We should see things with a longer lens, and be strategic about how we take care of our bodies.

Maintaining a healthy body is much better than treating a late stage chronic illness.

We have all heard this: “Prevention is better than cure.” But most of us don’t realize it until it’s too late.

People should wake up and start giving their bodies better treatment by doing good exercise and not eating junk food.

Remember, doctors can treat you once you get the illness. But before that, it’s your solemn duty to try your best to avoid any illness.

Don’t depend too much on the healthcare system for the simple reason that its business model isn’t in one hundred percent favor of your health or your bank account.

Medicines or any other treatment is important to cure an illness, but just to make sure that you remember it, try to avoid illness from happening in the first place at all costs.

Always focus on the long game.

Lesson #2: Notice the signs of health decline early on in your life to avoid future suffering.

People miss a lot of small signs of health decline.

Our bodies are intelligent machines. They give us signals when something is not right in our bodies.

So when there is deterioration in health, it will give certain signals.

And it’s up to us to catch them early. Because prevention is always better than cure.

The first sign of health decline is a loss of cognitive abilities.

In simple words, as you get older, you start forgetting things and lose your mind at times.

Older people struggle with simple mathematical calculations and remembering past events.

For some people, their personalities change as they get older because of these problems.

The changes aren’t always very drastic. It’s a gradual loss in cognitive capacity.

It means that you won’t lose your memory in one day. Slowly, it will begin to fade over the years.

The second form of deterioration in health is the loss of physical capabilities.

When you start getting a bit older, you naturally lose your muscle mass, bones and joints become weak, and digestion or metabolism also slows down. You struggle to carry heavy objects and get tired very easily with very little effort.

Things that we take for granted become very difficult.

For example, when we are young, we can easily walk whenever we want without even thinking about it. But old people have to think twice before getting up and walking, as their body structure becomes weak and their muscles get strained easily. Movement becomes difficult for them. Even the lungs don’t function properly, which causes difficulty breathing and ultimately results in a lack of oxygen during movement.

The more oxygen we can take, the better we move.

Wondering how?

All the systems in our body rely on oxygen to make energy. If our blood didn’t move the oxygen we breathe into our organs and tissues, we wouldn’t be able to carry out normal functions such as moving our muscles, digesting food, or thinking.

Of course, people who maintain their bodies with regular exercise over the years experience these problems way less than those who don’t do anything.

The third form of decline is “bad emotional health.”

Obviously, when someone has these many physical problems due to old age, it’s hard to feel good emotionally.

Even young teens are depressed these days, and here we are talking about old people who feel lonely and helpless.

You might be wondering what the point of discussing this is.

The point is that if we notice any of these signs in our bodies, it’s an alert that we aren’t living right.

All of us ignore health until there appears a problem we can’t ignore.

To increase longevity, we have to pay attention to the subtle signs our body gives us and prepare ourselves with a proper strategy.

For example, if you put on muscle mass with the help of exercise and a proper diet, even if you lose some muscle mass with age, you will be in a much better position than most people, and your chances of living longer are high.

Older people with less muscle mass are more likely to get severe injuries after accidental falls.

Lesson #3: We are overconsuming sugar in different forms without even realizing it.

The modern environment is rife with factors that encourage the consumption of sugar.

Some of them are:

  1. Ubiquitous Availability: Sugary foods and beverages are readily available almost everywhere in abundance, from grocery stores to gas stations to vending machines. This accessibility makes it easy to indulge in sugary treats frequently.
  2. Marketing and Advertising: Companies often heavily market sugary products, especially to children, through colorful packaging, enticing advertisements, and endorsements by popular figures. These tactics can create strong cravings and desires for sugary foods.
  3. Convenience Foods: Many convenience foods, such as packaged snacks, fast food, and ready-to-eat meals, contain high amounts of added sugars to enhance flavor and palatability. These foods are often cheap, easily accessible, and require minimal preparation, making them attractive options for busy individuals.
  4. Social Norms and Celebrations: Sugary foods are often associated with social gatherings, celebrations, and holidays. Whether it’s birthday parties, office gatherings, or holiday feasts, sugary treats are frequently served, contributing to their overconsumption.
  5. Stress and Emotional Eating: In times of stress or emotional distress, many people turn to sugary foods for comfort due to their ability to temporarily boost mood and alleviate negative feelings.
  6. Lack of Nutritional Education: Many people are not fully aware of the detrimental effects of excessive sugar consumption on health. Without adequate nutritional education, individuals may unknowingly consume large amounts of sugar in their diets.
  7. Food Deserts and Socioeconomic Factors: In certain areas, access to affordable, nutritious foods may be limited, leading people to rely on inexpensive, sugary options that are more readily available.

Overall, the modern environment is structured in a way that promotes the overconsumption of sugar through a combination of factors such as availability, marketing, convenience, social influences, and a lack of education.

When you combine this with the lack of movement and undersleeping, it’s no wonder that more and more young people are getting unhealthier these days.

If only we fix our bad habits and start educating ourselves more about what we are putting inside our bodies, we can avoid a lot of problems.

Cravings for sugar are influenced by a complex interplay of biological, psychological, and environmental factors. Understanding these factors can help individuals manage their cravings and make healthier food choices.

Many people think they don’t consume much sugar, but food product companies today are smart and adding sugar with different names like corn syrup, brown sugar, etc. to confuse customers.

If you eat things like fruit juices, pasta sauces, protein bars, soft drinks, etc., then you are already consuming a lot of sugar.

Even the products that claim they are sugar-free also contain sugar these days.

Such food products try to portray themselves as healthy alternatives, but they are not.

It doesn’t matter in what form you consume sugar; it’s still sugar.

And too much sugar is not good for our health. It’s that simple.

Lesson #4: Not all cholestrol is evil.

Cholesterol often gets a bad reputation in popular health discourse, primarily due to its association with cardiovascular diseases like heart attacks and strokes.

However, it’s important to recognize that not all cholesterol is evil, and in fact, cholesterol is an essential component of our bodies with various vital functions. Here’s a closer look at why not all cholesterol is harmful:

  1. Structural Integrity: Cholesterol is a crucial component of cell membranes, providing structural integrity and fluidity. Without cholesterol, cells would become too rigid or too permeable, compromising their function. In this way, cholesterol plays a fundamental role in maintaining the integrity and function of every cell in our bodies.
  2. Hormone Synthesis: Cholesterol serves as a precursor for the synthesis of steroid hormones, including cortisol, aldosterone, and the sex hormones (estrogen, progesterone, and testosterone). These hormones play essential roles in regulating metabolism, immune function, stress response, reproductive processes, and other vital physiological functions.
  3. Vitamin D Production: Cholesterol is a precursor for the synthesis of vitamin D, a hormone-like vitamin that plays a critical role in maintaining bone health, supporting immune function, and regulating calcium levels in the body. Vitamin D synthesis begins in the skin when cholesterol is exposed to ultraviolet (UV) radiation from sunlight.
  4. Bile Acid Synthesis: Cholesterol is used by the liver to synthesize bile acids, which are necessary for the digestion and absorption of dietary fats and fat-soluble vitamins. Bile acids emulsify fats, allowing them to be broken down into smaller particles that can be more easily absorbed in the intestines.
  5. Cell Signaling: Cholesterol is involved in cell signaling pathways, influencing various cellular processes such as proliferation, differentiation, and apoptosis (programmed cell death). Cholesterol-rich lipid rafts within cell membranes serve as platforms for signaling molecules and receptors, facilitating cellular communication and coordination.
  6. Brain Function: Cholesterol is particularly abundant in the brain, where it plays crucial roles in neuronal function, synapse formation, and neurotransmitter release. Adequate cholesterol levels are essential for maintaining cognitive function, memory, and overall brain health.

While cholesterol is necessary for these vital functions, problems arise when there is an imbalance in cholesterol levels or when certain types of cholesterol become elevated.

High levels of low-density lipoprotein (LDL) cholesterol, often referred to as “bad” cholesterol, can increase the risk of atherosclerosis (the buildup of plaque in arteries), whereas high levels of high-density lipoprotein (HDL) cholesterol, often dubbed “good” cholesterol, are associated with a reduced risk of cardiovascular disease.

Therefore, it’s not that all cholesterol is evil, but rather that maintaining a balance and proper ratio of different cholesterol types is crucial for overall health. Lifestyle factors such as diet, exercise, and medication (when necessary) can play important roles in managing cholesterol levels and reducing the risk of cardiovascular disease.

Lesson #5: The notion that cardiovascular diseases only affect older individuals and we need not concern about it at a young age is a dangerous myth.

While it’s true that the risk of CVDs tends to increase with age, there is growing evidence to suggest that these conditions can and do occur in younger adults, including those in their 20s, 30s, and 40s.

Ignoring the potential impact of CVDs at a young age can lead to missed opportunities for prevention, early intervention, and improved outcomes.

Here’s why it’s essential to debunk this myth:

  1. Rising Incidence in Younger Adults: There has been a concerning trend of increasing CVD incidence and risk factors among younger adults in recent years. This includes conditions such as hypertension, obesity, diabetes, and dyslipidemia, all of which are significant contributors to cardiovascular risk. Sedentary lifestyles, poor dietary habits, stress, and other modifiable risk factors prevalent in younger populations have contributed to this rise.
  2. Early Onset of Risk Factors: Many of the risk factors for CVDs, such as high blood pressure, high cholesterol, and smoking, can develop early in life and gradually worsen over time. Young adults who engage in unhealthy behaviors or have a family history of CVDs may already be at increased risk, making it crucial to address risk factors and promote healthy habits from a young age.
  3. Impact of Lifestyle Choices: Lifestyle factors play a significant role in the development of CVDs, and habits formed in youth can have long-term consequences. Poor dietary choices, lack of physical activity, excessive alcohol consumption, and smoking can all contribute to the development of CVD risk factors and increase the likelihood of experiencing cardiovascular events later in life.
  4. Silent Progression of Disease: CVDs often progress silently, with underlying damage accumulating over many years before symptoms manifest or serious complications occur. As a result, young adults may not be aware of their cardiovascular risk until they experience a heart attack, stroke, or other adverse event. Early detection and intervention are essential for preventing or mitigating the progression of CVDs.
  5. Impact on Quality of Life and Productivity: CVDs can have profound effects on individuals’ quality of life, productivity, and overall well-being, regardless of age. Young adults affected by these conditions may face physical limitations, emotional distress, financial burdens, and decreased life expectancy. Preventing CVDs early can help preserve health and enhance longevity.
  6. Opportunities for Prevention and Intervention: Addressing CVD risk factors and promoting heart-healthy lifestyles early in life can significantly reduce the likelihood of developing these conditions later on. Public health initiatives, healthcare interventions, and individual behavior changes aimed at preventing CVDs can yield substantial benefits for individuals, families, and society as a whole.

In conclusion, the belief that cardiovascular diseases only affect older adults is a dangerous misconception that undermines efforts to promote heart health and prevent premature morbidity and mortality.

Recognizing the importance of cardiovascular health at all ages is essential for implementing effective prevention strategies, improving outcomes, and reducing the burden of CVDs on individuals and communities.

Lesson #6: Avoid chronic inflammation in your body to avoid deadly diseases like cancer.

Before we learn how to avoid cancer, let’s understand what actually happens during cancer.

Normally, cells in the body divide and grow in a controlled manner to replace old or damaged cells. However, in cancer, this process goes awry, leading to the formation of a tumor or mass of abnormal cells.

These cancer cells can invade nearby tissues and organs, and they can also spread to other parts of the body through the bloodstream or lymphatic system, a process known as metastasis.

There are over 100 different types of cancer, each with its own set of characteristics, risk factors, and treatment approaches.

Common types of cancer include breast cancer, lung cancer, prostate cancer, colorectal cancer, and skin cancer. Treatment options for cancer may include surgery, chemotherapy, radiation therapy, immunotherapy, targeted therapy, hormone therapy, or a combination of these approaches, depending on the type and stage of cancer and other individual factors.

Therefore, early detection through screening tests and awareness of potential symptoms are critical.

If you want to avoid cancer, you should try to avoid obesity and type 2 diabetes, as they increase the risk of various types of cancer like liver, pancreas, etc.

Any kind of inflammation in the body creates an environment for cancer.

This is why it’s important to get our metabolic health in order first.

Normally, when people find out they have cancer, it’s already too late, and it has already spread to other vital areas of the body.

It’s a silent disease that keeps growing its roots. And we only see symptoms in later stages in the form of tumors.

Also, we must make sure that our immune system is healthy.

Such diseases can only grow if our immune system army is unable to properly fight these cancer causing monstrous cells.

Treatments for cancer are limited.

Therefore, the best strategy is to just prevent it from happening.

The author says that the first rule is “Don’t get cancer” and the second rule is “Catch it as soon as possible.”

This rule also applies to other chronic diseases as well.

Hopefully, medical science is improving rapidly, and maybe someday we will be able to cure this disease entirely.

Lesson #7: Exercise is the most powerful longevity drug.

Exercise is often hailed as the most powerful longevity drug, and for good reason.

Beyond its well-known benefits for physical fitness and weight management, regular exercise has profound effects on overall health and longevity, influencing multiple physiological systems and processes in the body.

From reducing the risk of chronic diseases to enhancing mental well-being and preserving cognitive function, the impact of exercise on longevity cannot be overstated.

One of the key ways in which exercise promotes longevity is by reducing the risk of chronic diseases, which are major contributors to premature mortality worldwide.

Regular physical activity has been shown to lower the risk of developing conditions such as heart disease, stroke, type 2 diabetes, hypertension, and certain types of cancer.

Exercise helps to maintain healthy blood pressure, cholesterol levels, and blood sugar regulation, while also promoting cardiovascular health by strengthening the heart muscle, improving circulation, and reducing inflammation.

By reducing the burden of chronic disease, exercise can significantly extend both lifespan and healthspan—the number of years lived in good health.

Moreover, exercise plays a crucial role in maintaining optimal body composition and metabolic function, which are important determinants of longevity.

Physical activity helps to build and preserve lean muscle mass, which is essential for metabolic health, mobility, and functional independence as we age. By increasing muscle mass and boosting metabolism, exercise can help to prevent age-related weight gain, sarcopenia (loss of muscle mass), and metabolic disorders. Additionally, regular exercise enhances insulin sensitivity, allowing cells to efficiently use glucose for energy and reducing the risk of insulin resistance and type 2 diabetes.

Beyond its physical benefits, exercise has profound effects on mental health and cognitive function, both of which are closely linked to longevity.

Physical activity stimulates the release of endorphins and other neurotransmitters that promote mood elevation, stress reduction, and overall well-being. Regular exercise has been shown to alleviate symptoms of depression and anxiety, improve sleep quality, and enhance cognitive function, including memory, attention, and executive function.

By promoting mental resilience and cognitive vitality, exercise can help to maintain independence and quality of life well into old age.

Furthermore, exercise exerts its longevity-promoting effects by influencing various cellular and molecular pathways involved in aging and longevity. Physical activity has been shown to activate anti-aging pathways such as AMP-activated protein kinase (AMPK) and sirtuins, which play key roles in cellular energy metabolism, stress resistance, and longevity.

Exercise also promotes mitochondrial biogenesis and function, leading to increased cellular energy production and improved oxidative stress resistance.

Moreover, exercise-induced changes in gene expression and epigenetic modifications may contribute to its anti-aging effects by modulating inflammation, DNA repair, and other cellular processes.

It’s important to note that the benefits of exercise for longevity are dose-dependent, meaning that the more physical activity you engage in, the greater the benefits.

However, even small amounts of exercise can have significant health benefits, and it’s never too late to start reaping the rewards of regular physical activity.

Whether it’s brisk walking, jogging, cycling, swimming, dancing, or strength training, finding enjoyable activities that you can incorporate into your daily routine is key to maintaining long-term adherence and maximizing the longevity-enhancing effects of exercise.
