How long do humans really live?

Oldest surviving birthday star: 130 years old India discovers the world's longest-lived person (2002-07-31 10:34 (10:34 AM) According to residents of Brown village in Himachal Pradesh, northern India, the old lady living in this village, Devgi Devy, is at least 130 years old.

If her age could be confirmed, she would be the longest-lived person in the world, 14 years older than one of the world's longest-lived Chinese women known. How long do we really live? American scientists believe that even with the continuous progress of science, it will be difficult for humans to live up to 100 years, and it will not become a reality for at least the next century.

The average life expectancy of people born in this century is 85 years. Oleshanski, a professor of public health at the University of Illinois at Chicago, said there is no miracle drug, hormone, antioxidant, genetic engineering or biotechnology in the world today that could increase human lifespan to 120 or 150 years, as some have predicted. Hefrick, an expert on the issue of longevity at the University of California, San Francisco, completely agrees with Oleshanski's view that the claim of "super-longevity" of human beings is simply "nonsense."

But Oleshansky does not deny that there are some facts that are still encouraging. He said at the annual meeting of the American Association for the Development of Science in San Francisco that since 1900, the average life expectancy of humans has increased by 30 years due to improved medical care. For example, the life expectancy of an American girl born in 1900 is only a few years, while that of a girl born in 1995 has reached 79 years.

In a report published in an upcoming issue of the journal Science, Oleshanski said that babies born in France and Japan would not live to be 100 years old until at least 200 years later; Babies born in the United States will not be able to join the centenarian club until 600 years later. The reason for this difference is that the rate of decline in mortality varies among the three countries. From 1985 to 1995, the mortality rate fell in France, in Japan, and only in the United States.

Based on this data, the average life expectancy of French people will reach 85 years by 2033, Japan will be 2035, and the United States will be 2182 years. According to the records, the person who lived the longest to date was a French woman named Calmet, who died in 1997 at the age of 1997. The Queen Mother of England is also one of the few examples of longevity.

According to Professor Heflick, life expectancy and life expectancy are two different concepts. Lifespan refers to how long a person can live; Life expectancy, on the other hand, refers to the average number of years that a person born in a given year is expected to live. The maximum lifespan of a human being is about 125 years.

Even if the most common causes of death in humans, such as cancer, heart disease and stroke, are eliminated, life expectancy will increase by up to 15 years, and then people will die from aging. He believes that the next big leap in human lifespan will only come if biological researchers discover how to slow down the aging process and make this discovery work for all of humanity.

156, the longest life ever recorded in the world.
