Health care is a shortcut to longevity.

With the continuous progress of society, the continuous improvement of human living standards, and the improvement of science and technology and medical and health level, after basically eliminating infectious diseases, the life expectancy of human beings has been greatly improved in a relatively short period of time. "Life is seventy years old" has become history, but now it is "a hundred years old is not strange, ninety is not rare, eighty is not old, and seventy is still a younger brother".

From the perspective of modern science, immortality and youth can only be a beautiful myth, but people can find out the causes of aging and death through research, so as to take corresponding measures to control the aging speed, raise the threshold of death and prolong life.

According to the metabolic law of nature, it is impossible to live forever, but it is entirely possible to prolong life. It is generally believed that people will die when aging reaches the death threshold, but the relationship between aging and death is difficult to determine, because different people have different aging speeds, and the death threshold is also drifting (the death threshold depends on living environment, causes of death, accidents and other factors).

Through long-term research by scientific workers, it is found that the modern life span of human beings 15% depends on genetic factors, 10% on social factors, 8% on medical conditions, 7% on climate and environmental factors, and 60% on lifestyle and mental state such as exercise and diet.

In other words, there are many factors to achieve a long and healthy life, but the most important one is determined by itself. Just as many medical scientists advocate that the "golden key is in your own hands" for health and longevity. That is, what we ancients called "neutralization is healthy" and "those who can neutralize live long".

The so-called "neutralization" means that physical and mental activities such as eating, drinking and thinking about emotions should be moderate and just right. Through many horizontal surveys and long-term longitudinal observation of 106 1 case of elderly people with long life span, combined with many different longevity reports and health preservation discourses at home and abroad, we finally come to a conclusion that healthy longevity is the result of a comprehensive effect of many factors, the core of which is to follow a good lifestyle, and its central content can be summarized as "persisting in activities, being optimistic, living regularly, having moderate nutrition and quitting smoking"

Therefore, lifestyle, that is, health preservation, has become the key to health and longevity. In this respect, we need to follow the four cornerstones put forward by the World Health Organization: reasonable diet, moderate exercise, smoking cessation and alcohol restriction, and psychological balance.
