With the continuous progress of scientific and technological means, the upper limit of human life is constantly being refreshed, and on the whole, the human life expectancy is correspondingly extended. Of course, this has a certain relationship with the individual's physical functions and changes in living conditions and environment. Human exploration of the secret of longevity has not stopped, but it has to be said that the reasons affecting human life expectancy are very complex, and there is still a lot of room for exploration on human lifespan. So how long do people live? How can we extend the lifespan of an individual as much as possible?

<h1 class="pgc-h-arrow-right" data-track="4" How long can the elderly live >? It mainly depends on whether we can overcome the hurdles of these two years</h1>
How long does an individual actually live? This cannot be generalized, and it has something to do with the difference in individual physical fitness. However, if the elderly can cross the two age thresholds of 73 years old and 84 years old, they will definitely live a long life.
"Seventy-three, eighty-four, the king of Yama will not tell himself to go!" The elderly are convinced of this statement, believing that as long as they successfully pass the age of 73 and 84, these two age thresholds will surely lead to longevity. Obviously, such a statement sounds very superstitious, but this statement actually has traces.
In the I Ching, it is mentioned that everything in the world has a regular cycle, and the I Ching believes that the life cycle of a person is 11 years, so in the year in which the life cycle is connected, that is, the year in which people call the "year of life", the human body is prone to major changes such as illness.
The age of 73 and 84 is exactly the transition year to complete the life cycle, so for the elderly is two thresholds of life, but if the elderly can cross these two thresholds, it will naturally smoothly enter the next life cycle, and naturally it will be able to prolong life.
<h1 class="pgc-h-arrow-right" Data-track="6" What factors can affect the length of human life >? </h1>
The length of life and heredity have a certain influence relationship, if the parents have a longer lifespan, then affected by genetics, children will have a greater advantage in life expectancy. From the perspective of the proportion of influence, the proportion of the influence of parents' genetic genes on human life expectancy has reached 15%.
The living environment in which the human body is located will also have an impact on its life span, for example, the level of medical technology has improved, and the medical environment has improved significantly, so this can naturally help the human body to be in a healthier physical state, which will naturally help prolong life. For example, if the social environment in which people live is relatively stable and harmonious, then the life of the human body will be correspondingly extended.
Lifestyle will also have an impact on the length of life, especially nowadays, many people do not pay attention to healthy living habits, often there are overeating, sleeping late, smoking and drinking and other bad habits, then these unhealthy lifestyles will not only induce body diseases, but also accelerate the loss of aging and life. Compared with other factors, the proportion of lifestyle influence on longevity occupies a more important position.

Ensuring a regular and healthy work and rest is very good for physical health and life extension. For example, from 10:00 to 12:00 p.m. is the time for the body's immune function to recover, if you can enter the sleep state at this stage, then this will naturally be very helpful for physical health care. The ancients said that "sunset and rest, sunrise and work" has a certain truth, catering to the life routine of the human body's biological clock, which is more conducive to physical health. Staying up late will not only reduce immunity, but also overdraft the body, and go to bed early to rest for a longer life.
Adherence to a healthy diet is also beneficial for physical health. Meat and vegetarian combination, control salt and oil intake, and maintain a light diet principle, which can not only reduce the body's digestive burden, but also ensure that the body is in a relatively light and healthy state. Meat and vegetarian collocation, eat more vegetables and fruits of the diet, not only can reduce the probability of obesity, but also can reduce the incidence of chronic diseases such as cardiovascular and cerebrovascular diseases.
Moderate exercise can improve the body's metabolism and keep the body in a "youthful state". Both young people and middle-aged and elderly people should be part of the life of doing things. Studies have shown that walking for more than three hours a week can reduce the risk of cardiovascular disease by 30% to 40%, and can also reduce the occurrence of diseases such as Alzheimer's disease and breast cancer. It can be seen that insisting on exercise is the most effective way to maintain a long and healthy life.
In addition, keeping a happy mood and feelings of well-being will also be very good for prolonging life. Studies have shown that a good family atmosphere as well as intimate family relationships can be compared to the risks associated with the human body to some extent. For example, some cancer triggers are related to long-term emotional depression. Nowadays, people's lives are more stressful, but the more in this case, the more they should pay attention to their own health care, and it is necessary to adhere to healthy living habits.
