How many years is the best life for human beings, please thank you

Primitive society: the average life expectancy of human beings is 15 years, because human beings have little strength and cannot resist natural disasters, diseases, wild beast attacks. The average life expectancy of human beings was only 20 years BC, only 25 years old in ancient times, and the average life expectancy of human beings was only 40 years until the century.

1700: The average life expectancy of humans is 35 years 1800: The average life expectancy of humans is 37 years It can be seen that the life expectancy of humans in 1700-1800 has not increased.

The reason is that although it is possible to avoid disasters such as wild beasts, because of the low level of science and technology, life is hard, and there are no effective measures against diseases. At the beginning of the 20th century, human life expectancy leaped from 40 to 61 years. In 1985, the average life expectancy in the world reached 62 years.

The average life expectancy of the world population is expected to increase at a rate of about one year every five years. 1995-2000 is the year, 2000-2005 is the year, 2005-2010 is the year, 2010-2015 is the year, 2015-2020 is the year, and 2020-2025 will be over 70 years old. By the end of this century, China will be one of the top 10 longest-lived countries in Asia, with an average life expectancy of years.

Expert**2300 years of average human life expectancy of 95 years can also be added: regional issues, such as the Japanese people's longevity is due to the level of science and technology, economy and eating habits. The short life expectancy of South Africans is due to diseases such as AIDS.

In ancient times, there were related Taoists and emperors refining relevant pills to seek students. With the development of science and technology in modern times, although people realize that they should prolong their life through scientific health preservation methods, the realization of longevity is sometimes a fantasy. So, how old are humans according to scientific research?

Modern people can live up to about 70 to 100 years.

No one in the world has lived to be 100 million years old. The world's longest-lived person on record was the French lady Jeanne Calment, who died in 1997 at the age of 122.

In 275 B.C., the average life expectancy was 26 years; By 1900, the average life expectancy had risen to 49 years; In the past 50 years, the unprecedented prosperity of material civilization has increased the average life expectancy by nearly 20 years.

This person is Li Qingyun, who died at the age of 256! However, the authenticity of this matter still needs to be verified, after all, such an age is very amazing today, compared to ancient times.

The life span of human beings is only half a year, but the world's longest-lived people also live to be more than 140 years old, so for us humans, we need to keep exercising to make our bodies reach a very healthy level, and we can live for a long time.
