In sports, after the age of 20, women's sports ability only drops by 2% every 10 year. However, after the age of 20, men's muscle activity ability will drop 10% every10 years, so by the age of 60, their exercise ability has dropped by 40% compared with that of the age of 20.
Nuns live longer than other women. Coal miners: The average life expectancy of restaurant waiters and journalists is very short. The older a person is, the less likely he is to catch a cold. With the growth of age, people become less and less sensitive to pain. Regardless of men and women, there are three industries that will perform better after the age of 40, namely: musical comedy, novel creation and construction industry.
When people reach the age of 60, the energy used by the brain is equivalent to a 10 watt light bulb. When people reach the age of 60, their taste and smell will deteriorate by 40-5096. People who are dissatisfied with their lives may increase their premature death by 10%. The average person lives to 74 years old, and the food he eats in his life is about equal to the sum of the weights of six elephants. Qu, a geriatrician at the University of California, said that eating a nutritious breakfast every day would make people live longer.
Since ancient times, the average life expectancy of human beings has changed as follows: Stone Age: 19 years old. Ancient Europe: 20, at least 30 years old. Bronze Age: 2 1.5 years old. 16th century: 27.5 years old. 17th century: 29 years old. 18th century: 28.5 years old. 1801-1880: 35.6 years old. 1891-1900: 40.6 years old. 1901-19/kloc-0: 44.8 years old. 1924- 1926: 56 years old. 1932- 1936: 59.8 years old. 1946- 1949: 57.7 years old. 1970- 1980: 77.3 years old. 1981-1992: 77.8 years old.
According to historical data, experts estimate that the average life expectancy of China people in Xia and Shang Dynasties is no more than 18 years; 20 years of Western Zhou, Qin and Han Dynasties; The Eastern Han Dynasty was 22 years old; Tang is 27 years old this year; Song is 30 years old; Green 33 years old; He was 35 years old before liberation. After liberation, according to the survey of 1957, the average life expectancy of China people has increased to 57 years, 68 years in 198 1 year, and 68.97 years in 1985, which is nearly 1 times higher than before liberation, including 66.99 for men.
How many years can humans live? In the 65438+1960s, the upper limit of human age was about 100 years old. In 1960s, the upper limit was about 105 years old. Today, human life can be extended to about 108 years. The newly published popular science reading "Human Revolution" is analyzed from the perspective of genetic science that is popular all over the world. The life span of people can reach 160 or 70 years old. Where is the basis for human beings to live to 160 and 70 years old? Some scientists have shown that the life span of various animals is related to their own growth, which is about 5 to 7 times that of the growth period. The human growth period is 20 years and 25 years, so the life span should be 100 to 170 years. Some scientists believe that the maximum life span of mammals is about 14 to 15, so the natural life span of human beings should be 1 10 to 150. Some scientists have analyzed the number of cell divisions of embryonic cells, and think that the number of cell divisions of human beings is 50, with an average division cycle of 2.4 years, so the life span of human beings is 120 years. Some people think that the average gestation period is 266 days, and the highest point of human life is 167 years.
Not only that, according to research, the extension of human life also benefits from many factors such as good health environment and developed medical care. Therefore, with the continuous development of science and technology, especially the continuous improvement of medical technology, the limit of human life will continue to increase.
