How many years does the average person live, and how many years does the average person live?

Science shows that the average life expectancy of a person is 120 years! You know that kind of old death! The body's functions are exhausted!

But in reality, very few people live that long! Illness, accidents and more are inevitable! The average life expectancy of a person is now around 70.

Life is in your own hands, pay more attention to your body! That's true. Now the average life expectancy of a person is around 80!

The average life expectancy of Chinese is 75 years old, and it should reach 80 years in the next 10 years.

No one can know how long any one person will live. But we can use statistical methods to ** the average life expectancy of a certain population, which is called life expectancy. If we want to know the life expectancy of a certain population, the most direct and accurate way is to calculate the average life expectancy after all of them have died.

But this is unrealistic, because it means that we have to wait more than a century before we can do statistics. In practice, demographers use an indirect, less accurate but much simpler approach to statistics. For many years, many countries** have counted the number of births and deaths per year, as well as the age of the deceased.

The census also counts the number of people still alive at each age. Taken together, this information allows demographers to calculate the risk of death and the probability of surviving to the next year for people of each age. This probability of survival forms a "life table" that shows an estimate of the life expectancy of people of any age.

This estimate is known as "cyclical life expectancy" and varies from year to year. The average life expectancy of Chinese in 2001 was years, compared with years in 1981, an increase of 4 years in 20 years. Before the founding of New China, the average life expectancy of Chinese was only 35 years.

According to World Population Prospects: The 2000 Revision, published by the United Nations Population Branch, the average life expectancy in developed countries is now 75 years, while in developing countries it is 63 years. This shows that China's average life expectancy is close to the level of developed countries, and some regions have exceeded the average level of developed countries, with years for men and years for women.

In 2011, the national statistics showed the average life expectancy of Chinese.

According to researchers, the average age of men is 68, and the average age of women is 72.

The average person lives for 70 years.

Maintain optimism by the living environment, diet and daily life.

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 longevity at the University of California, San Francisco, fully agrees with Oleshanski, saying 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 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 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 by 2035, and the United States by 2182. 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 how many years a person born in a given year is expected to live on average.

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.

Oleshansky said that the most realistic approach at the moment is to study how to extend the healthy period of human beings. Today, the health of a 65-year-old is the same as that of a 60-year-old in 1960. For human beings, the quality of life may be more important than how long they live.
