"Enjoying life" is the goal that human beings have been striving for, but how old is a person's "life"? Since ancient times, countless scientists have deciphered this "first topic" of human life. Although there are different textual research methods, most of them fix the end point of human life at around 120 years old.
How long can people live?
"In fact, examples in real life have answered this question." Professor Chen Naihong of China Academy of Medical Sciences told the reporter of Life Times that the oldest person in history is a French woman Jean-Louise? Carmen, 122 years old 164 days; The oldest person in history is Chiyo Izumi of Japan at the age of 120 years and 237 days. "This is surprisingly consistent with the conclusions drawn from scientific research."
Chen Naihong said that there are currently three internationally recognized views on how long the elderly can live:
First, represented by Aristotle, an ancient Greek philosopher, it is believed that the ultimate age of a person is related to his growth period or maturity, and his life span should be 5-7 times that of the growth period, that is, 100- 140 years.
Second, Japanese scientists have concluded through long-term research that there is a biological law between human life expectancy and sexual maturity. The former is about 10 times of the latter, and can reach 108- 145 years old.
Third, American scientist Haier? It was put forward by fleek at 196 1 He believes that human cells will age and die after dividing 50 times. The cycle of normal cell division is about 2.4 years/time. According to this calculation, people's life span should be about 120 years. China's traditional medicine has also verified this truth: Shangshu puts forward "long life is 120 years old", that is, you can live to 120 years old. Ji Kang, a famous health expert in the Jin Dynasty, also thinks that "longevity" can reach 120, "both ancient and modern".
"In addition, people can live Takuya is related to the speed of the heart beating. Generally speaking, the slower they jump, the longer their life may be. " Chen Naihong said. In recent years, some scientists have been throwing out shocking theories. For example, Russian scientists believe that the average life expectancy of people can reach 280 years; British scientists point out that the longest life span of a person can reach 1000 years.
