Life expectancy varies from country to country. The average life expectancy of people in developed countries is very short. In recent years, the average life expectancy in China is 73 years. Spirit is very important for people over 50. Relieve the pressure, establish a harmonious family environment and temperament, get well, there will be fewer diseases, parents and children will live in harmony, and with proper physical exercise, it is very possible to lead a normal life at the age of 80 or 90. As for those who live to be over 100, after all, it is very rare. First, very few people can live to be over 1 14 years old. It is estimated that there is only one in every 2 1 100 million people. No one knows whether these people will live longer than Mrs. Carmen. We can only set the longest life span of human beings at 122 years old. Secondly, modern scientists estimate the maximum life span of human beings by various methods, such as sexual maturity 8 ~ 10 (14 ~ 15 years old), growth period 5 ~ 7 times (20 ~ 25) and cell division 2.4 times (40 ~ 60 times). However, due to the influence of diseases and living environment, there is still a big gap between human life expectancy and the highest life expectancy, but with the development of science, the average life expectancy of human beings will gradually approach or reach the highest life expectancy.
