To support a person's life, a Chinese idiom, pinyin is y yíy m \ngtiānnián n, which means to maintain a person's life. This is a line from the Beijing Opera "The Woman of Men Yang".

Keeping your age is maintenance. The age of the supporter is the life span, and there is no specific age designation for the supporter, as long as he is older. Helping the elderly is a commendatory term, which is suitable for the elderly.

Age "Age:

"Tiannian" is a meaningful proposition about life in ancient China. Time is a natural time, that is, the life span of nature. People's life span has a certain time limit, and ancient health experts and medical experts think it should be between 100- 120 years old. But in fact, the age limit of 120 years old is consistent with the general longevity survey data.

There are few examples of exceeding this physiological limit since ancient times. I often hear that "keeping one's life" is just a kind of rhetoric and dream, and it also refers to maintaining one's life, that is, there is no specific age designation, just be older.

However, with the development of science and technology, modern medicine has also answered the question of "how old a person can live" from different angles. According to the calculation method of growth period, the maximum life span of mammals is 5-7 times of its growth period, and the growth period of human beings is 20-25 years.

Therefore, according to this calculation method, people's natural life span should be 100~ 175 years old, so most experts think that people's natural life span should be considered as a good life span as long as it exceeds 90 years old.
