Introduction: Birth, old age, sickness and death, this is the law of nature, no one can escape, everyone will experience aging, this is the common destiny of human beings, we often say that the birth of life indicates the advent of aging.
Countless people have searched for the secret of longevity in their lives, but often in vain. In fact, many elderly people know that it is a rare blessing to be able to enjoy their old age in peace, which not only gives us a long time to taste life, but also makes us feel warm in care and love.
However, as we get older, our bodies are undergoing subtle changes, and the lifespan of humans seems to be quietly shortening.
For the sake of good health, many elderly people focus on daily maintenance, and they aspire to have a long physique so that they can enjoy their old age happier and healthier.
Walking and getting enough sleep are key to maintaining good health.
But a retired doctor pointed out that in addition to these, if you want to truly achieve longevity, you need to pay attention to two seemingly insignificant things, and what are these two small things? Let's listen to the doctor.
In fact, there is no fixed answer, because everyone's physical condition, lifestyle, genetics and other factors are different, so for a person, the age of longevity will also vary from person to person. At the same time, we also need to put longevity in perspective.
Although longevity is a goal that many people pursue, the length of life does not equal the quality of life. Although some people have a shorter lifespan, they are able to live a full and meaningful life, leaving behind valuable ideas and contributions; And some people live a long life, but they live in pain and suffering, which is not of much value.
Therefore, we should focus on how to make our lives more meaningful and worthwhile, rather than just pursuing the length of life. To do this, we need to maintain a positive mindset, a healthy lifestyle, good relationships, and meaningful careers and hobbies, so that we can truly enjoy life and make our lives more exciting.
Mankind's quest for "immortality" has been around since ancient times, but why has it not been achieved yet? Telomerase, a miraculous substance found in living organisms, reveals the mystery to us.
Telomerase, as the name suggests, is an enzyme that is able to repair telomeres. Telomeres are structures at the ends of chromosomes, and as the cell ages, the telomeres will gradually shorten, eventually causing the cell to stop, triggering senescence.
However, some organisms in nature are able to use telomerase in the body to maintain the length of telomeres, thereby prolonging lifespan. Lobsters, for example, are rich in telomerase enzymes, allowing them to live an astonishing 100 years.
If humans could also have enough telomerase, would they be able to achieve immortality? Unfortunately, making large quantities of telomerase is an extremely difficult and arduous task. In addition, telomeres may be just one of the many factors that affect longevity.
In fact, scientists have found that many other factors such as genetics, lifestyle, environment, etc., can also have an impact on longevity.
In order to achieve an increase in human lifespan, we need to continue to explore these factors that affect lifespan and use the power of science to find solutions.
Although we can't completely reverse the aging process, by improving our lifestyle, maintaining a healthy mindset, and sticking to scientific exercise, we can extend our life to a certain extent and make our lives better and more fulfilling.
Genetics:Genetic factors have a certain impact on the lifespan of humans, and some genetic variations may affect the lifespan of people;
Lifestyle:Lifestyle is one of the main factors affecting life expectancy, such as: eating habits, smoking, drinking, exercise, sleep, psychological state, etc.
Environmental factors:Environmental factors including climate, geographical location, air pollution, water quality, etc., will affect the lifespan of human beings;
Disease:Disease is an important reason for shortening life expectancy, and the prevention and prevention of chronic diseases are essential to prolong life expectancy;
Nutrition:Inadequate or excessive nutrient intake can have an impact on longevity. Reasonable nutritional intake is conducive to prolonging life;
Social Factors:Social factors such as social environment, support, and loneliness can also affect a person's lifespan.
Walking and sleeping more than enough is not enough to maintain longevity, and while the benefits of these healthy habits cannot be overlooked, longevity does not depend solely on these factors.
First of all, walking more is indeed an effective way to promote health, moderate exercise can enhance cardiorespiratory fitness, increase metabolic rate, help control weight, reduce the risk of disease, however, to maintain longevity, walking is not enough.
Secondly, sleeping more is not a recipe for longevity, and while getting enough sleep is essential for physical recovery and mental health, sleeping too long or too little can have a negative impact on health. Studies have shown that not getting enough or too much sleep can increase the risk of disease and affect life expectancy, so it's also important to get a moderate amount of sleep.
In summary, in order to maintain a long life, there are many factors that need to be considered, and walking and sleeping more are part of a healthy life, but it is equally important to maintain the following two ways.
Eat a sensible diet
In the fast-paced modern life, people often neglect physical health because of their busy work, however, a reasonable diet, as an important part of a healthy lifestyle, plays a vital role in people's longevity and health. Scientific studies have shown that a proper diet can not only provide the nutrients your body needs, but also reduce the risk of disease and prolong life.
First of all, a reasonable diet can help to control weight, and modern people often suffer from obesity due to excessive intake of high-calorie, high-fat and high-sugar foods.
Obesity is the root cause of many chronic diseases, such as cardiovascular disease, diabetes, etc., by adhering to a reasonable diet, people can consume the right amount of calories and nutrients, avoid excessive obesity, and thus reduce the risk of disease.
Secondly, a reasonable diet helps to prevent chronic diseases, such as cardiovascular disease, cancer, etc., which are one of the main causes of death, and a reasonable diet can provide the body with enough nutrients such as antioxidants and dietary fiber, which can help prevent the occurrence of chronic diseases. For example, a diet rich in vegetables, fruits, and whole grains can help reduce the risk of cardiovascular disease and cancer.
Be in a good frame of mind
Maintaining a good attitude is one of the secrets to longevity, how a person's state of mind directly affects his quality of life, in modern society, we often face various pressures and challenges, if you can't maintain a good attitude, it is easy to fall into anxiety, depression and other negative emotions, which have a great impact on health and longevity. If you want to maintain a good attitude, you must first learn to adjust your emotions, when we encounter setbacks or difficulties, do not let negative emotions prevail, but learn to calmly analyze problems and find solutions.
At the same time, we must also learn to release stress, such as relaxing through exercise, reading, etc., so that our mood becomes happier and more relaxed.
In short, maintaining a good attitude is one of the secrets to longevity, we should always pay attention to our emotions and mentality, learn to adjust ourselves, and make our mood more happy and relaxed, only in this way, can we have a healthy, happy, and long life. 
In April 2020, a research team from Shanghai Jiao Tong University conducted an in-depth analysis of the physical sign data of 9,520 Chinese people, and the results showed that the number was as high as 561% of respondents with a BMI index greater than 30 were classified as obese.
The study found that in obese individuals, the risk of developing high blood pressure gradually decreases as the leg circumference increases, suggesting that leg fat may have a positive effect on the body's metabolism and help maintain blood pressure at a relatively low level.
In addition, the study also found a strong association between leg fat and heart health in obese individuals.
In 2023, this view was further supported by a study published in the British Medical Journal (The BMJ), which noted that people with more belly fat accumulation had a relatively higher risk of death.
In contrast, people with higher fat content in the hips and legs had a lower risk of death. Specifically, for every 10cm increase in waist circumference, the risk of death increased by 11%; For every 5cm increase in thigh circumference, the risk of death was reduced by 18%; For every 10 cm increase in hip circumference, the risk of death is reduced by about 10%.
The findings suggest that abdominal obesity is positively associated with a higher risk of death, while those with higher hip and thigh fat content are more likely to have a longevity advantage.
The chief physician of the Affiliated Hospital of Fudan University once pointed out that the ratio of human chest height is 107:1；The hip-to-height ratio is 113:1；The waist-to-height ratio is 073:1 is the range of normal health, and these data are important for people to understand their physical condition and take corresponding measures to maintain health.
Stable facial features
Studies have found that people with symmetrical faces and balanced facial features are more likely to live a long and healthy life in the future, which may be because this characteristic indicates that a person's growth and development process is more stable and the functions of various organs in the body are more coordinated.
Earlobes are plump
The earlobe is a holographic reflex area of the human body, it is related to various organs of the human body, if a person's earlobe is plump and firm, it means that his body is in good health, the organ function is normal, and he has the potential for longevity.
Eyebrows are thick
The thickness of the eyebrows is related to the hormone secretion in the human body, if a person's eyebrows are thick and black, it means that his endocrine system is normal, and the hormone secretion is balanced, which helps to maintain the health of the body and prolong life.
73 and 84 are the two hurdles of the old man" is widely circulated, and its origin is difficult to trace, perhaps, this saying is similar to the proverb "seven.
Ten. Three, eighty-four, immortality is also in bed".
Some people also believe that this is because the ancient sages Confucius and Mencius lived to be 73 and 84 years old respectively, so these two ages are regarded as "two hurdles", however, we cannot rely on experience and hearsay alone for health preservation methods. The scientific basis is equally important.
From a medical point of view, there are indeed two key stages of human aging, but not at the age of 73 and 84, but at the age of 60 and 78.
According to the research statistics released by the National Cancer Center, there were 3.92 million new cases of cancer in China in 2015, of which the highest age group was 60 to 64 years old!
In addition, the China Cause of Death Surveillance Dataset 2021 also revealed that the mortality rate in the age group of 60 to 64 years has increased rapidly, reaching 79349 100,000, with the increase of age, the wear and tear of the body is also intensifying, of which around 60 years old is the age group with the greatest fluctuations in physical health, and after the age of 70 it enters a stable period of ten years, and after the age of 80 there will be fluctuations.
Another key age is 78 years old, Stanford University research found that the speed of human aging is not uniform, there are three special aging acceleration periods, including 78 years old, which means that 78 years old is an important inflection point for human aging and health.
Therefore, when people enter the age of 78 years old, their life has entered the "life expansion period", only by taking the right health care methods, it is more likely to live a long life, at this stage, people need to pay more attention to physical health, through scientific and reasonable health care to delay aging, improve the quality of life.
