People are born old, sick and die, although it can not be avoided, but the length of human life is still associated with many factors:

1. Genetic.Children generally inherit some of the characteristics of their parents to a greater or lesser extent. Longevity is also inherited, and genetic factors can be considered important in determining longevity. Generally, if the parents or the immediate family above them live long, the next generation of children may also live longer, but excluding deaths caused by external forces.

2. Environment.This factor is also more important, a person lives in a place where the water, soil, air, etc. are suitable for human survival and free from pollution, and this kind of living environment can also relatively help prolong life.

3, Personality.Character can also be said to be fate, character, can determine the person's mental outlook, if usually positive, optimistic people, peace of mind, emotional changes, such as the character of the person, not easy to get sick. On the contrary, the character of irritability, stubborn bigotry, temperamental and so on such people, easy to cause some of the disease occurs, long-term, it will cause a greater impact on the human body health, and even reduce life expectancy.

4. Diet. Disease enters by the mouth, there are problems with diet, directly affecting people's health. Some people in order to make more money, resulting in food plus hygiene substandard, harmful to human health.

5. Lifestyle.The pace of life continues to become faster and faster, so that people from all aspects of the pressure also increased, a variety of bad habits such as diet, irregular work and rest, always partiality, stay up late and so on. Lack of exercise, too tired, a lot of smoking, drinking, overindulgence and so on. All will make the body produce disease, long so, affect the life of people.

People who often skip breakfast will also be prone to shorter life expectancy. In addition to not eating breakfast is not conducive to people's ability to think, etc., easy to lead to gastritis, gallstones and other diseases, jeopardizing people's health.

6. Jobs.Some jobs expose you to things that are detrimental to your health, which can lead to illness over time.

The above is a summary of some of the factors affecting the life of people, longevity or not anyone can not decide, but usually pay attention to stay away from all the things that affect health, is always good for the body.

Human longevity is first and foremost directly related to genes, with one study showing a 40% correlation between our lifespan and genes.

In addition to genetics it is also related to the environment and how developed the city is throughout the day. See the table below

This table tells us that life expectancy is not only related to genes and mitigation, but also to the degree of development of the city, and the medical and living conditions in the developed cities are also related to some extent.

The overall living environment, how developed the city is, is correlated to the all-day life expectancy per capita in that city, but genetics are more important when it comes to each individual specifically.

Genetic issues, that is, whose family were we born into? Who are our mom and dad? But can we choose? We can't! That's why genes are innate and can't be changed.

Living environment, for the vast majority of people, it is almost impossible to want to go to the north to live in the north, or want to go to the fresh air of the paradise can go, we in order to survive or in order to live, we have to stay in a certain city can not be changed.

But what determines our life expectancy is also closely related to our lifestyle, the reason is simple, a healthy life can reduce diseases, reduce diseases can prolong life; unhealthy lifestyle will induce diseases, many diseases, especially chronic diseases, will shorten the life expectancy if they are not actively and formally controlled. So for each of us as individuals, it is our living habits that determine life expectancy.

First, tobacco and alcohol

There are so many studies on how smoking shortens life expectancy. The average life expectancy of smokers is reduced by about 10 years compared to non-smokers; smoking itself increases the risk of cardiovascular disease and increases the risk of cancer; severe cardiovascular disease, and most cancers shorten life expectancy, so smoking seriously affects our life expectancy.

Drinking alcohol has always been debated, and the latest mega-analysis of 28 million people around the world confirms that the idea that drinking alcohol in moderation is good for your health is completely non-existent! That is to say, even a small amount of alcohol can affect health and life expectancy, but of course drinking is certainly relatively better than smoking, and alcohol should be consumed sparingly and things should be known more often.

Second, diet

You may have heard of the Mediterranean diet, how did this diet come about? People on the Mediterranean coast have fewer cardiovascular diseases than in other places, and their natural life expectancy is relatively longer. Nutritionists and epidemiologists have given clear advice: vegetable oils instead of animal oils, more vegetables and fruits, grains and cereals, low-salt, low-fat, low-sugar diets, supplemented with appropriate dairy products, fish, nuts and so on is conducive to a healthy diet. These are the themes of the Mediterranean diet. So what kind of diet will have what kind of body, a healthy diet will naturally have a healthy body, will naturally have a relatively long life.

Third, sports

In the latest research, sedentary inactivity poses the same dangers as smoking and cardiovascular disease, with a 52% increased risk of death for those who sit ≥8 hours per day, relative to those who sit <4 hours, and an 80% increased risk of all-cause mortality for sedentary people compared to those who exercise! Sedentary people have a 107% increased risk of cardiovascular disease death compared to those who exercise! Long-term adherence to aerobic exercise can, increase the number of hemoglobin in the body, improve body resistance, anti-aging, enhance the efficiency of the cerebral cortex and cardiopulmonary function, increase fat consumption, prevent atherosclerosis, reduce the incidence of cardiovascular and cerebral vascular diseases, and is conducive to blood pressure control.

Fourth, status

Modern people are the pressure of life, the rhythm of life has changed, all kinds of pressure, stay up late irregular life and so on. On average, people who sleep 7-8 hours a night have the longest life expectancy; while those who sleep less than 4 hours have the shortest life expectancy.

Fifth, weight

Obesity is an independent risk factor for the three highs and cardiovascular diseases, and obesity can lead to many diseases, so weight control is important for slowing down aging.

Sixth, marriage

Studies have shown that married and loving couples have a long life expectancy, while unmarried and divorced people who live alone have a shorter life expectancy accordingly. Sexual repression has an impact on life expectancy, but unrestrained sexual indulgence also affects life expectancy, only normal and controlled sex life can improve the body's immune function, which is conducive to a long and healthy life.

VII. Other

People who are socially active live longer; those who are withdrawn and unsocialized have a correspondingly shorter life expectancy. When you reach a certain age, you must have regular checkups to detect many non-fatal diseases and intervene early so as not to aggravate them. For example, hypertension, diabetes, hyperlipidemia, early detection and early treatment, so as to avoid the development of cardiovascular and cerebrovascular diseases affect life expectancy.

Eighth, the most important thing is the state of mind, the most important thing is to be happy

There are many factors affecting the mindset, but the most important is still self-regulation, that is to say, people have to rely on themselves, no one can help you adjust your mood. Anyone will have pressure, anyone will have difficulties, anyone will be unhappy; but it depends on how you face the pressure, how to face the difficulties, how to learn to become happy from unhappy.

There are many factors that affect our life expectancy, but we can't change our genes, we can only develop healthy habits from childhood and cultivate a happy and joyful mood every day!

Not only should you live a healthy and long life, but you should also live a long life!

From ancient times to the present, long life, has been the constant pursuit of mankind, but can reach the centenarian, is only a handful of. What are the factors that affect human life expectancy? There are five main categories of subjective and objective factors that are recognized as affecting human longevity:

The first is genetic: human genes are basically the same, with the improvement of living conditions and medical standards, the life of human beings is gradually prolonged, now, the general life expectancy is between 70-85 years. But some family members have a longer life expectancy, their average life expectancy is more than 85 years old, there are family is shorter, the average life expectancy in not more than 50 years old, of course, these are not fixed. With the continuous change of the marriage relationship that is long-lived family and not long-lived family marriage cross, family members life expectancy is constantly changing, which means that people and life expectancy is closely related to genetics. It is the first factor in determining life expectancy.

The second is environmental factors: water, soil, vegetation, air and other environmental factors in the living area are the second factor determining life expectancy. Many longevity villages have a large number of centenarians because the local living environment is very livable. On the other hand, cancer villages have a large number of malignant diseases, mostly due to environmental pollution.

The third is psychological factors: due to personality, work, life reasons, some people love to get angry when things often angry; some people are too tolerant of things, not happy for a long time in the heart; some people are too sensitive to things too good to the bull's-eye, depressed; some people have too much mental stress, can not be transferred in a timely manner or defuse; there are people with too little mental capacity, fear of overweight, and so on, so that their own gas depression injury, and affect life expectancy. And affect life expectancy. Mentality determines fate, mentality also affects life expectancy.

The fourth one is food safety: nowadays, there are many people who, for the sake of momentary economic benefits, produce substandard food, use industrial materials at will, and produce and process unhygienic and unsafe food, thus harming human health and jeopardizing life expectancy.

The fifth is lifestyle: our society nowadays has a lot of work pressure and a faster pace. Many people do not have to develop a good living and eating habits, but also affects the health of the body. Like bad eating habits, hungry one meal, hot one cold one bite, long-term partiality, etc.; like some people over-nutrition, lack of exercise; like often overworked, long-term rest is not good; like not see a doctor for a disease, have a disease without medication, have a test without checking the body; like excessive smoking and alcohol, excessive indulgence, etc.. These bad lifestyles are harmful to health and affect life expectancy.

If we have an optimistic mindset, a happy and fulfilling marriage, and family harmony, these are also helpful in prolonging life.

Thanks for the answer. The progress of living standard and material abundance make people have higher requirements for themselves, that is, they want to live longer so that they can have more time to enjoy life. Exactly what factors determine the length of a person's lifespan, I will share my opinion with you.

The length of human life is related to many factors, I believe that genetic inheritance accounts for the main part, excluding accidental factors, genetic inheritance mainly determines the length of human life. Some studies have shown that the relationship between genes and life expectancy is closely related, and 61 genes related to aging have been identified so far. Although most diseases are not hereditary, the probability of their onset is inextricably linked to genes. Although genes play a major role in longevity, gene-determined longevity is by no means the result of the role of a particular gene, but the result of the integrated and balanced role of multiple genes, and gene expression can only affect longevity, and gene expression is affected by a variety of environmental factors inside and outside the human body. Therefore, living habits, diseases, emotions, external environment, diet and so on will all affect the expression of genes. Besides genes, living habits and diet are the biggest factors affecting life expectancy. Good living habits will make the body in a healthy state, do not stay up late, do not smoke, do not abuse alcohol, which can reduce the prevalence of various cardiovascular and cerebrovascular diseases. Appropriate exercise to speed up the body's blood circulation and promote metabolism. Meanwhile, diet has become another hidden danger to the health of modern people. Unhealthy high-fat, high-energy and high-sugar diets have become a major killer of health. Good longevity genes just give you a good start. There are four equally important factors that determine whether you live a long life or not: optimistic life, regular and reasonable diet, moderate exercise and regular medical checkups.

The life span of a human being needs to be maintained.

Human life expectancy should be 5 to 6 times the growth period, simple reasoning life should be able to live 100 to 120 years. With the enhancement of awareness of health self-protection, China's centenarians gradually increased, in fact, the secret of longevity is simple, easy to understand. That is, eat rough, sleep well, move a lot, mind flat. Longevity is the pursuit of everyone, but need to be maintained every day, to eat reasonably, sleep scientifically, move appropriately, balanced mind. Diabetic patients to make their own healthy long life is to try to adhere to, seriously, not sloppy. A long and healthy life means a healthy life, a better quality of life, the joy of life and the pursuit of life. Elderly diabetic patients and healthy old people, to do the same old, old, old and happy.

The maximum number of years a human can live is recorded throughout history, but not many are well documented. For example, Thomas Parr of England was a famous long-lived man in the 16th and 17th centuries. He was said to have lived to 152 years of age, but because of the lack of credible evidence, he was disproved by Young at the beginning of this century. Another example is Japan's Izumi Shige Chiyo, a famous longevity star of the last century who lived to be 120 years old, but Japan's "Longevity Recognition Committee" still has doubts about his birth date. There are some places in the world that are known as longevity zones, such as the Caucasus Mountains in the former Soviet Union, Hansa in the Himalayas of Pakistan, and Vilcabamba in the Andes of Ecuador, where the so-called centenarians or supercentenarians are more often than not less than a hundred years old, due to the lack of birth certificates, or to the interference of certain customs or social factors during the registration of births, which is not sufficiently trustworthy.

Xinjiang in China was also once considered a longevity zone.

However, the custom there is not to remember one's birth date, or to exaggerate one's age. Therefore, in the 1950s, the author participated in a survey and found that the number of centenarians was not as many as the census announced, and the highest age of the interviewed centenarians was only 105 years old. In the 1980s, two professors from the former Federal Republic of Germany, H. Frank and A. Schramm, who were visiting China, reported the results of their survey of hundreds of centenarians, whose ages were determined on the basis of reliable birth certificates. The oldest person interviewed was a woman of nearly 111.5 years.

They also followed up 301 centenarians and found that they could live an average of 21 to 26 months after turning 100. At home and abroad, there are many investigations on longevity, generally speaking, the maximum life expectancy of human beings does not exceed 120 years, of course, does not exclude individuals to break through this boundary, but after all, rare. China's Warring States medical book "Yellow Emperor's Classic of Internal Medicine" in the "100 years old" for the person's "days". Jikang's "health theory" pointed out that "on the life of a hundred twenty ancient and modern the same". This means that there has been no major breakthrough in human longevity over the centuries.

If we say without any assumptions, human life span is determined by fate.

Some people have a bad life, a young age suffered a military disaster, water and fire, car accidents are fiercer than a tiger ...... These are all life, right? Some people may be well-maintained, the body times great, the results go out for a walk, accidentally by the upstairs fell down a flowerpot, smashed to death.

However, if these contingencies are not taken into account, then I believe that the following are the factors that determine the length of a person's lifespan

1. Genetic factors

Genes are a very powerful thing, and the Chinese Academy of Sciences has specialized in the study of longevity genes. The Japanese have an exceptionally long life expectancy, which may have something to do with their genes.

2. Economic conditions

The better the economy, the better the medical care that the area and the people can enjoy. Life expectancy is naturally long.

3. Exercise, but not too much.

They say that life is all about exercise, but you can't work too hard. Those who work too hard often tend to overdraw their lives.

4. Early to bed and early to rise

Early to bed, early to rise, good health, this saying is really the truth. Look at those sudden deaths, many of them are poor rest and stay up late!

5. Meals should be rationalized.

Meat and veggies, not too salty or oily, fresh fruits and vegetables, or both.

6. Be in a good state of mind

Being responsive to the times, positive and optimistic, and tolerant.

A medical professor once pointed out that there are five major factors affecting human health: genetics, social environment, natural environment, medical conditions and lifestyle. Lifestyle accounts for 60% of the total. You can imagine how much lifestyle affects human health.

　　Many times, people often short life expectancy is attributed to disease and aging, but in fact, the reason why people did not reach the age of one hundred, the biggest reason is mostly due to an unhealthy lifestyle, if you can maintain a healthy lifestyle, disease and aging and how will you find you so quickly? If you want to live a long life, these 4 points "health scripture" must see, early to see early benefit.

　　Point 1: Eat Regularly

　　Diet as the body's energy supply, if you eat well, people will also live more and more young. For diet, always keep in mind the saying, "Eat enough in the morning, eat well in the middle, and eat less in the evening." Breakfast is the most important, so you must eat every day, but also to eat enough; and dinner is recommended to eat less, otherwise it is easy to obesity. However, nowadays, many people because of work, often irregular diet, and then suffer from all kinds of diseases. Therefore, if you want to live a long life, don't slack on your diet, pay attention to a balanced diet, do not picky about food, eat more fruits and vegetables.

　　Point 2: Ensure sleep

　　Sleep can restore the body after a day's labor, but if you regularly stay up late, how can you relieve your body's fatigue? On the contrary, it will aggravate the burden on the body, and gradually the body will age faster. If you want to live more and more young, it is best to ensure that you go to bed before 11:00 every day, and also get up early in the morning, and also develop the habit of taking a nap at noon.

　　Point 3: Don't smoke or drink

　　Cigarettes and alcohol contain substances that accelerate the aging of the body, which is the most unhealthy lifestyle and one of the biggest causes of cancer, so be sure to break the habit of smoking and drinking.

　　Point 4: Get less angry

　　Mental health is also an important influence on physical health, a person who is often angry, long-term negative emotions, it is easy to suffer from mental illnesses, gradually affecting the body's metabolism and endocrine, affecting the life expectancy, as the saying goes: "Smile, ten years less." If you can always maintain an optimistic mindset, I believe that longevity will be more "pro" you.

The natural life expectancy of human beings is projected according to the laws of biology, the individual life expectancy of human beings seldom reaches the boundaries of natural life expectancy, and the individual life expectancy of people in general is very different and varied. So, what factors are related to the life expectancy of human beings? Many medical doctors, biologists, philosophers, and researchers in other disciplines around the world have devoted themselves to the study of this great subject and have achieved considerable results. Generally speaking, the factors related to human life expectancy are congenital (endogenous) and acquired (exogenous), but, specifically, they are endless and diverse, with most scholars emphasizing the effects of heredity, gender, personality, as well as disease, living environment, lifestyle (such as diet, nutrition, exercise, hobbies), and other factors.

More and more statistics prove that long-lived people often have a long-lived family genealogy, Bell in the investigation of the Hyde family found that the children and grandchildren of this family, in the people who have lived to 80 years old, half of their fathers are more than 80 years old; Hungary, there is a farmer at the age of 195 years old, his children in has been 155 years old; Japan, there is a farmer called Manabe, in 1798, himself has been 194 years old, wife 173 years old, son 153 years old, grandson 105 years old; in China's guangxi bama county of 51 longevity of the elderly, there are pairs of people's relatives are long-lived. Therefore, many scholars believe that the natural life expectancy is the characteristics of the race, the human life expectancy is mainly determined by genetic factors, human racial characteristics, genetic code can determine human aging, and thus and life expectancy is closely related. A perusal of many population life expectancy statistics almost unanimously shows that women live longer than men.

In 1979, the average life expectancy in the United States was 70 years for men and 77.6 years for women; in 1985, it was reported that the average life expectancy in Japan was 74.84 years for men and 80.46 years for women. The life expectancy of human beings is obviously different because of the difference of gender, and many scholars in the world are always interested in this issue.

American scholars have used the viewpoint of genetics to illustrate the immune advantage of female physiology. The male sex chromosome consists of an X chromosome and a Y chromosome, and the female sex chromosome consists of two X chromosomes, and the human immune function gene exists in the X chromosome, therefore, the female sex chromosome has double the immune function of the male sex chromosome, so it has a strong resistance to disease, coupled with the fact that the male sex chromosome has a higher basic metabolism than the female sex chromosome, which is an important factor of the female sex life expectancy. There are also many scholars believe that human social factors on the male life expectancy is also relatively large, female houseworkers accounted for the vast majority of men engaged in occupational labor intensity; male lifestyle and hobbies (tobacco, alcohol, etc.) and women have significant differences; life expectancy impact of large tumors (eg, lung cancer, hepatocellular carcinoma, etc.) cardiovascular diseases, etc., men are more. Thus, it is not surprising that the life expectancy of women is higher than that of men. When many geriatric scholars conduct surveys on the long-lived elderly, they almost always raise the question that, in addition to the special character of the long-lived, most of them are cheerful, open-minded, mentally happy, quiet and emotionally optimistic. Character is a unique psychological quality of human beings, constraining all the psychological activities of human beings. There have been scholars will be divided into type A and type B personality, type A personality of people fast and sharp, fast-paced work, high efficiency, but prone to impatience, this character of people, suffering from coronary heart disease, however, fewer people suffering from cancer; B-type personality of people, gentle and calm. Work slowly and methodically, love to think hard, this kind of personality traits of people, easy to suffer from mental trauma, often emotional depression, pessimism, negativity, suspicion and other abnormal psychology. This classification method focuses on the attention of the innate factors, while the training of the acquired life environment, the accumulation of life experience, etc., also has a very important role in the development and transformation of character. Even for the elderly, if they can improve their ability to adapt to the social environment, their personality type can be changed. Such as some of the leading cadres with heavy responsibilities, in the workplace, once the fast pace of work, do things quickly and quickly, they retired, is an ordinary member of the family, there is not a lot of work to do, if you can face reality, correctly deal with the various contradictions in the life of the community, adapt to the new environment, will certainly produce a new inculcation of the character and remodeling, and thus the possible formation of a new type of character. Of course, there are some people whose personality types are hard to change. The influence of different personalities on life expectancy is still a mystery to be further studied by experts.

Disease can make people die before they are old, and disease and disability are important factors affecting the natural lifespan of human beings. In a person's life, there is almost no one who has not suffered from disease. There are tens of millions of long-lived people in the world who have never suffered from disease in their lives? No matter how old a lifer is, it is impossible for a person to die without disease. Disease is inevitable in a person's life (some diseases can also make the body produce lifelong immunity, for example, people who have suffered from mumps, measles, generally will not suffer from the disease for a second time in their lives), and there is no shortage of people who suffer from chronic diseases to become long-lived people. In the January 4, 1981 "Health News" translated "Arab" series of information, introduced the late British politician Winston Charles, he was born on January 4, 1874, was a premature baby, at about 10 years old, "bones as thin as a wood, please the disease, wind and rain can not support the cold and summer," such a person can live for how long? ? Charlie did not fall in front of the disease, he was strong-willed, not discouraged, not backward, for decades as one day to exercise, and finally became a strong person to overcome the disease, to the age of 91 years old through life.

Although the disease is an important factor affecting life expectancy, but is not the only factor, suffering from chronic diseases, it is also possible to become a longevity. The relationship between ecological environment and longevity, a long time ago, factory people's attention, China's ancient "Nei Jing" has said: "a state of gas, life and death of life and death of different, the terrain so that the potential is also ...... high of its gas life, the lower of its gas is premature". That ancient people have recognized the terrain height and life expectancy related. According to statistics, the life expectancy of the urban population in modern industrially developed countries is generally about five years less than that of the rural areas, which may be related to the "three wastes" pollution and noise interference from urban industries.

It can also be seen from many statistics that there are more long-lived people in certain regions of the world; in Azerbaijan, there were 63 centenarians for every 100,000 people in the early 1980s, which may be due to the fact that mountainous areas are characterized by such features as temperature, humidity, pressure, sunlight, atmosphere, hydrology and geography that are conducive to human longevity, and that the environment here is secluded and the air is clean, which enhances the health of the human body. Some scientists have found that there are anions in the air of mountainous and rural areas that are beneficial to longevity. It is also believed that the chemical content of water and food in certain areas is conducive to longevity. All these suggest that living in a beautiful and unpolluted environment is an important condition for longevity.

Human growth, development and life activities, the need for adequate nutrients and energy, all of which, depends on the food protein. Fats, sugars, vitamins, minerals and water and other nutrients; the human body to resist disease, engaged in various activities, but also need to be rich in nutrients; to old age, the aging organism is more need to choose to consume some high-quality protein. Therefore, every moment of life activities, are inseparable from a certain amount of nutrients, long-term malnutrition in the state of people is wood may live long. Nutrition for human longevity is certainly important, but when people's living standards continue to improve, more and more affluent people, nutritional status is also getting better and better, if the intake of excess nutrients, the body's energy metabolism will be out of balance, leading to obesity. Hyperlipidemia, hypertension, coronary. Heart disease, diabetes and many other diseases occur, posing a great threat to human longevity. Only reasonable and balanced nutrition is good for health, and excess nutrition is not conducive to longevity. Reasonable exercise can be fitness, healthy body is beneficial to longevity, which is known to all, and people's interests and hobbies are often ignored. Generally speaking, long-lived people usually have more hobbies.

In Japan, a special survey was conducted on the interests and hobbies of centenarians, and about 81 per cent of them enjoyed participating in social activities and cultural, sports and recreational activities during their young adulthood. It is believed that this can postpone and slow down the aging of brain cells. Hobbies mainly rely on human cultivation, the elderly need to cultivate some hobbies, such as ornamental flowers, birds, fish breeding, painting, calligraphy and participate in a variety of cultural and sports activities, which not only increase knowledge, but also can cultivate temperament, exercise will, increase the fun, enrich life. When people reach old age, most of them leave their workplaces, and the content of life is more likely to be monotonous, and a small number of elderly people are also prone to loneliness and melancholy psychological state.

Cultivating one's multifaceted interests and hobbies, and taking part in various cultural, sports and social activities as appropriate are important ways to achieve health and longevity. Many other factors related to longevity can also be cited. In short, human longevity is affected by many intricate factors, and any single factor may be a decisive factor for a certain person, but it can only be regarded as an important factor, or even a non-relevant factor, for each person. For example, some people living in environmentally beautiful areas have become long-lived old people, and the living environment has a great influence on these long-lived old people, but not everyone living in environmentally beautiful areas can live a long life, and the life expectancy is affected by heredity, exercise, diet and other factors. Therefore, we should look at every factor conducive to longevity and unfavorable factors from a comprehensive point of view. As long as everyone creates favorable factors for a long and healthy life and overcomes unfavorable factors, everyone can strive for a long and healthy life.

As far as the current research evidence goes, it is first and foremost determined by genetic factors. Children tend to live longer when their parents live longer, suggesting that longevity is largely determined by the genes passed on to us by our parents. On the flip side, if parents suffer from a chronic disease, there is a certain likelihood that their children will suffer from the same disease. Not all diseases have a family history, but they account for a larger percentage, so doctors will ask about the patient's parents' medical history during physical examinations so that they can be more targeted.

In addition to genetic factors, there are environmental and behavioral factors. For example, the level of education determines life expectancy to a certain extent, with better educated people living longer. There are also social status and economic conditions; people with high social status and good economic conditions have better health and enjoy better medical services, which are reflected in their life expectancy. Behavioral factors such as whether or not they smoke, abuse alcohol or drugs, eat a healthy diet, and are exposed to frequent hazards and accidents are all reflected in life expectancy. Studies have also found that children of long-lived parents have high levels of education and good lifestyle habits, so genetic, environmental and behavioral factors are interconnected.

However, this does not mean that there is no hope for children to live longer if their parents have a short life expectancy. Parents can die prematurely due to accidents or illnesses that, if prevented and detected early, would not have been premature. With the advancement of science, some diseases that are fatal to parents can become less fatal. In addition, by changing living and eating habits, improving education, social status and economic status, one can make a great improvement in environmental and behavioral factors compared to one's parents, and then life expectancy will increase, for example, when rural people move to the city, life expectancy will generally be extended.

People want to live longer, in fact, the vast majority of us do not live to life expectancy because of disease, if we can do a good job of disease prevention and control, and to prevent accidents, so that we can live to life expectancy, to live to more than 90 years and more than 100 years of age is not a dream but a reality for most people.

It's not that you're striving for longevity, it's that you were meant to live that long.

This is a very good question! You can look up my previous answers on the length of human lifespan, in which my main point is that, broadly speaking, the length of human lifespan is determined by 3 major factors: firstly, genetic factors; secondly, disease factors; and thirdly, accidental injuries and deaths.

This Q&A is a little more specific, and my point is that, apart from casualties from accidents, there is a strong correlation between how long people live and their genes. Because longevity correlates with longevity genes; disease also correlates with genes.

Here's my argumentation process, just for reference.

Correlation between longevity and longevity genes

First of all, although scientists have yet to fully understand the complete genetic profile of human longevity, the view that human longevity is genetically related has not changed; the existence of longevity genes in humans has not changed, and scientists around the globe are still publishing longevity genes that have been found in human beings one after another.

To summarize, there are basically 2 views regarding the conceptual description of longevity genes, which are for reference only.

1. Longevity gene defense function said:The idea is that there are multiple genes in our bodies that govern the length of our lives; and that those genes that are able to control our body's defenses well despite the harshest of environments in our bodies are the genes we respectfully refer to as thelongevity gene. It is because of this tenacity that they have shown in the face of adversity that our health has been continuously improved and successfully blocked the attack of aging on the growth and vitality of our bodies, enabling us to remain youthful in our 70s, 90s, and even at 100 years of age.

2. Longevity gene repair function said:The reason for aging, according to this view, is that our body's normal defense as well as repair mechanisms deteriorate with the passage of time.

However, in some people, there are such genes or genomes that strengthen self-defense and repair mechanisms at all ages.

These genes, or genomes, maximize our chances of overcoming disease by optimizing our own survival functions; and, the longer these genes, or genomes, remain active, the longer they enhance our health and extend our lives.

And these genes, or genomes, are the ones that exist in long-lived people, those longevity genes that work against the aging genes, called Longevity genes in English.

For example, in a survey conducted by the Medical School of the University of Kiel, Germany, the gene "FOXO3A" and four bases (A, T, C, G) are present in the DNA of long-lived people.

Correlation of diseases with genetic predisposition

The above are some of the points that we have talked about, the correlation between longevity and longevity genes. Here we will talk about some evidence of the correlation between diseases and genes, and I will only take the most common "three highs" diseases: hypertension, diabetes mellitus and hyperlipidemia as an example to demonstrate my point of view, for reference only.

1. Genetic correlates of hypertension

The so-called hypertension is a pathology in which the blood in our body, during its flow through the blood vessels, exerts a pressure on the walls of the blood vessels that is consistently higher than normal.

To date, scientists around the globe are still unclear about the pathogenesis of hypertension, so the cause of most clinical hypertensive patients, to date, remains undefined.

Some ideas about the relationship between high blood pressure and genetic predisposition are listed below for reference only.

This view suggests that the apparent familial clustering of hypertensive patients is due to the polygenic inheritance of hypertension, and it is the presence of these inherited genomes that makes the inheritance of hypertension more likely.

One study, after investigating the families of hypertensive patients, found that the probability of their children developing hypertension in the future was as high as 45% if both parents were hypertensive; if one parent was hypertensive, the probability of their children developing hypertension was 28%; and if both parents had normal blood pressure, the probability of their children developing hypertension was only 3%.

The genes that have been identified, and that may be associated with the genetic predisposition to hypertension are AGT, eNOS, ACE, ANP, NPRC, ET-2, and other genes.

2. Genetic correlates of diabetes

The current clinical definition of diabetes mellitus is that it is a group of disorders of carbohydrate, protein, and fat metabolism caused by absolute insulin deficiency, or relative insulin insufficiency, and/or impaired insulin utilization, with hyperglycemia as the primary marker.

From this definition, only the characteristics of pathological changes in diabetes are revealed, but the etiological mechanisms of diabetes, are not clarified.

Some ideas about the relationship between diabetes and genetic predisposition are listed below for reference only.

This view suggests that there is a clear genetic predisposition to diabetes, especially in type 2 diabetes, where there is cellular organization of a hereditary nature.

Studies have shown that the prevalence of diabetes is significantly higher in people with a family history of diabetes than in people without a family history of diabetes, and that children of families where both parents have diabetes are 15-20 times more likely to develop diabetes in the future than the general population.

Studies have found that there are just a few known genes that may be associated with genetic predisposition to diabetes: the CDKN2A and CDKN2B genes on chromosome 9, among others.

3. Genetic correlates of hyperlipidemia

The current clinical definition of hyperlipidemia given is that hyperlipidemia is defined as elevated triglycerides and/or total cholesterol in our plasma, which also includes elevated LDL cholesterol and decreased HDL cholesterol.

Similarly, the specific mechanism regarding the formation of hyperlipidemia has not yet been clarified, while it is believed that hyperlipidemia is related to genetic inheritance, and some of the following ideas are for reference only.

It has been found that hyperlipidemia is characterized by certain familial aggregation, and familial hyperlipidemia has genetic defects and a clear genetic predisposition, which ultimately leads to lipid metabolism disorders, and this type of hyperlipidemia, clinically, is generally referred to as familial hyperlipidemia.

The role of a healthy lifestyle in longevity

The above arguments show that longevity has a very strong correlation with genes.

So what role do the healthy lifestyles we promote on a daily basis play in a person's lifespan?

1. Healthy lifestyle makes your genes healthier

So-called healthy living happens, in a nutshell:Scientific diet, balanced diet, healthy hobbies, regular work and rest, moderate exercise, physical and mental well-being.

If you have longevity genes in your body, then cultivating and maintaining such a healthy lifestyle will make those longevity genes in your body, healthier and stronger.

On the contrary, if you do not cultivate and maintain such a healthy lifestyle, then even if you have longevity genes in your body, the longevity genes in your body will become unhealthy and weak because of your unhealthy lifestyle.

2. Healthy lifestyles make non-genetic factors healthier

Similarly, for some of the non-genetic factors in longevity, if you cultivate and maintain a healthy lifestyle, it will make those non-genetic factors healthier and stronger.

Conversely, if you don't cultivate and maintain such a healthy lifestyle, then it makes these non-genetic factors unhealthy and less powerful.

To summarize: in addition to accidental casualties, the length of a person's lifespan has a strong correlation with genes.
