How old does the average person live, and how old does the average person live now

Phew. If you are happy, you will live longer.

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.

Relevant data show that about 2,000 years ago, the average life expectancy of human beings was about 20 years. In the 18th century, it grew to about 30 years old; At the end of the 19th century, the average age was only around 40; In 1980, the average life expectancy of the world population had reached 61 years, 72 years in developed countries and 57 years in developing countries: in 1985, the average life expectancy of the world population had risen to 62 years, 73 years in developed countries and 58 years in developing countries. Iceland and Japan have the highest average life expectancy in the world, at 77 years each.

Scientists predict that at the end of this century or the beginning of the next century, the cancer problem will be overcome, and at that time, the average life expectancy of human beings will leap again, and the average life expectancy of the world's population will exceed 80 years. The top 10 countries with the highest life expectancy in the world are: Japan, Australia, Canada, France, Spain, Singapore, Greece, Israel, Italy and Sweden, all of which have an average life expectancy of more than 78 years.

Sierra Leone, the country with the shortest life expectancy in the world, had an average life expectancy of only 40 years in 1997, a full 40 years less than the world's longest-lived Japanese.

It doesn't matter how long it can live, as long as it spends every day happy, and the rest is left behind, and I don't think about it, I don't guess it, you know, I want to be happy, I want to be happy, and I want to grasp every day of my life.

Life expectancy in China is also 71 years for men and 74 years for men and women.

Today's average person lives to be 75 years old.

Not good on average. It's probably more than 60.

The average life expectancy of human beings is related to factors such as social institutions, socio-economic development, social health care measures, and scientific and technological progress. Before liberation, the average life expectancy of our people was about 35 years. After liberation, according to the statistics of the 1978 census, the average life expectancy of the Chinese people was 69 years for men and 69 years for women, which was nearly double that before liberation.

In 1980, the average life expectancy of the population in most parts of China exceeded 70 years, which was among the world's advanced levels. In addition to the political emancipation, the improvement of the economic situation, the improvement of living standards, and the improvement of sanitary conditions, the increase in the average life expectancy of the population in our country is also related to the dietary habits. The people's diet is mainly based on cereals, vegetables, crude fiber and vegetable oil, and refined cane sugar, animal fats and cholesterol account for a small proportion of the food.

This dietary peculiarity is beneficial in preventing the occurrence of cardiovascular diseases. According to statistics, among the causes of death, the most common cause of death after the age of 65 is cardiovascular and cerebrovascular diseases. Scientists believe that the onset of atherosclerotic coronary heart disease in Chinese people is 10-15 years later than that of Europeans and Americans, which may be related to the characteristics of this diet in China.

Therefore, when the standard of living continues to improve, it is beneficial to continue to retain this dietary structure to prolong life.

Thank you for the trouble to adopt!

Theoretically 150 years old Oldest surviving birthday star: 130 years old India discovers the world's longest-lived person (2002-07-31 10:34 Ocean Forum) According to residents of the village of Brown in Himachal Pradesh, northern India, the old lady who lives in the village, Davgie Devi, 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 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".
