How long does a normal person live?

People nowadays can live up to 150 years. The average age is 73 years. I won't know about it in the future.

Hehe. Geneticists at the University of Southern California recently announced that they have discovered a way to extend the lifespan of organic organisms, so that humans can live up to 800 years. Scientists say they have succeeded in extending the life of baker's yeast tenfold and could easily translate it into prolonging human life.

This method, which is reported to combine two human genes and reduce the amount of calories consumed by the human body (modifying the diet), has even begun human trials in Ecuador. According to the Public Library of Science (PLOS), a non-profit academic organization supported by numerous Nobel laureates and philanthropic organizations, it aims to promote the latest research in science and medicine from around the world, making it a public resource. According to detailed reports, a team led by USC project leader Walter Longo has created this yeast, and the yeast can live for 800 years without notice***.

This very important discovery will enable scientists to get closer to controlling and mastering all the cells and tissues related to human survival and health through human dietary adjustment and genetic changes, so as to achieve the purpose of prolonging life. The discovery of this method is a foundation that will open the door to human beings to transform life. Longo's team added a piece of baker's yeast to a prescribed calorie dose (mimicking human dietary regulation) and combined two human genes, RAS2 and SCH9, to react with the yeast.

The yeast is then aged, and at the same time two human genes are carcinogenic. After a long period of experimental research, Longo's research team found that the lifespan of yeast was 10 times longer, compared to the lifespan of normal yeast is only one week. Anna McCormick, director of the Genetics and Cell Biology Division of the National Society for Aging Research (NIA), said the National Society for Aging Research is pleased with their findings and will provide financial support for the research project, hoping that Long's research team can help scientists make drugs that can be used to prolong human life.

Baker's yeast is the best research medium for studying molecular changes and genetic composition of organisms. In recent years, scientists have discovered some important genes in yeast research, especially those that control aging and disease, and some genes have been successfully tested in mice and other mammals. It can be said that the study of yeast is the best tool for geneticists to explore the mysteries of life.

Longo's research team plans to further study the effects of increased longevity next year. Because there are many factors involved in prolonging life, and it is not clear whether this method is resistant to various bacteria and diseases. The most worrying is the possibility of mutations in both cells and genes, some of which are said to have been mutated in human tests in Ecuador.

At present, the impact of this method of prolonging life on human ethics also needs to be evaluated and studied, and some experts even point out that if human life is extended, it will affect the economic development of the human world.

The World Health Organization recently released the "2006 World Health Organization Report", which shows that the average life expectancy of men in China is 70 years, the average life expectancy of women is 74 years, and the average life expectancy is 72 years. According to the World Health Report 2006 released by the World Health Organization after surveying 192 countries and regions around the world, Japan, Monaco in North Africa, and San Marino in Southern Europe tied for the first place with an average life expectancy of 82 years, followed by five countries including Italy and Switzerland with 81 years of age. The country with the shortest life expectancy in the world is Zimbabwe in southern Africa, at 36 years.

According to the survey, there are now 16 countries around the world where life expectancy is more than 80 years, while 26 countries in Africa and Afghanistan have an average life expectancy of less than 50 years. The average age of Chinese is 75 years old, and 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.

According to the traditional Chinese saying: 70 years old is rare, and 70 years old is a threshold. With the improvement of living and medical standards, this boundary has been broken, however, the old saying goes: seven.

Ten. 3. Eighty-four, Hades does not call himself to go. Looking at the current lifespan of the people around you, it is basically in this range, generally between 75-85.

A person's normal life expectancy is more than 140 years old, but it is usually difficult to reach this number due to environmental influences, food, diseases and other factors, but there are still some long-lived elderly people, and the average life expectancy of Chinese is 75 years old.

1. What is it called?

Lifespan in a nutshell, lifespan refers to the time that a living being exists in the self-natural realm.

DAO is to say that lifespan refers to the concept of time when the life activities of living organisms exist in the whole process of containing nature. Living organisms follow the inevitable laws of the life cycle of birth, growth, and development, to aging and death, and humans are no exception. In fact, a person's lifespan is how many years a person lives.

The normal life expectancy is 120 years.

1.Reason: According to the principle of biology, the life expectancy of mammals is 5 to 7 times that of its growth period, and the growth period of human beings is calculated by the time when the last tooth grows out (20 to 25 years old), so the shortest human life expectancy is 100 years old, the longest is 175 years, and it is recognized that the normal life expectancy of a human should be 120 years.

2.Factors influencing lifespan:

1) Genetic factors are related to the average life expectancy of your parents, grandparents, and grandparents, which is normally slightly higher than the average.

2) Health factors, that is, whether you are healthy or not, whether you pay attention to healthy exercise, proper exercise is beneficial to the body, and at the same time improve your quality of life.

3) Psychological factors, to maintain a good attitude, not to sum up the length of life, to live a meaningful life, to maintain a good attitude, do more to help others, that feeling is also beneficial to people's health.

4) Environmental factors, that is, whether the living environment is good and healthy.

According to Bai's more professional report, it is speculated that the normal lifespan of a person should be 120 years old. As follows: Expert of the National DAO Cardiovascular Disease Research Leading Group.

According to the definition of the World Health Organization, before the age of 65, middle-aged people are counted as middle-aged, 65-74 years old are counted as young and elderly, 75-90 years old are considered formal elderly people, and people's life expectancy is 100-175 years old, and the recognized normal life expectancy of people should be 120 years old. Due to diseases and other reasons, the average life expectancy of human beings is less than 70 years, which is 50 years less than the normal life expectancy.

The longest-lived woman in history: The longest-lived woman in history with conclusive documentation is Jeanne Louise Calment of France. He was born on February 21, 1875 and died on August 4, 1997, at the age of 122 years and 164 days.

The lifespan of a normal person is about 100 years. The human brain and body are not fully developed until they are 25 years old, so many people want to change the age of 18 to 25.

Now the average life expectancy is about 78 years old, which varies from place to place, and is much lower in some places, which is related to the standard of living and the level of medical care.

The maximum lifespan should be 125 years old, but many people do not live and die because of illness.

: How many years does a person generally live?

In fact, people's life expectancy often does not reach the level said upstairs, the average life expectancy of the world population is more than 70 years old, the average life expectancy of the Chinese population is more than 60 years old, and Japan, which is closest to our race, has an average life expectancy of more than 80 years, which is 15 years higher than the average life expectancy in China, and there are 8,000 elderly people over 100 years old in Japan. Everyone can live to be 100 years old. But can you guarantee that you will always be healthy? We all know that wine is a poison that pierces the intestines, but don't you drink it?

We all know that color is a steel knife that scrapes bones, but can you? Qi is a tiger descending the mountain, who doesn't have something to worry about, can you not be angry? Money is the root and seedling of trouble, can you afford to buy a house without working hard to earn money?

How old a person can live at most depends on how good his mentality is, as long as he is not tired of fame and fortune, everyone can live to be 100 years old! acxvdfdxcx

At present, the average life expectancy in China has reached 75 years.

life, pronunciation: shòu mìng

Definition: The number of years of life. The latter is also a metaphor for the duration of existence or the duration of use.

Source: "Chu Ci Da Zhao": "Yongyi is a body, and life is guaranteed."

Historical Records: The Biography of Lislie": "Pray to the gods of the famous mountains to prolong life." "Tang Hanyu's "Ouyang Sheng's Lamentation":

Life is uneven, humane is common, and there is no difference between the side and the distance. ”

The so-called life span refers to the time of the body's survival from birth, growth, maturity, aging and even death, and is usually measured by age. Because there are certain differences in life expectancy between people, the average life expectancy is usually used when comparing the life expectancy of humans in a certain period, a certain region or a certain society. Life expectancy is often used to reflect the level of medical development of a country or a society, and it can also indicate the economic and cultural development of a society.

The normal lifespan of a cell is 120 years.

It is about 120 years old, but due to human birth, old age, illness, death, etc., and some external factors, the actual life expectancy of human beings is several years to decades shorter than the normal life expectancy. Therefore, it can be said that life is short in life, and we must learn to cherish life.

Biologists deduce that mammals live 5 7 times longer than their growth period. A person's growth period is calculated by the time it takes for the last tooth to erupt, with an average of 20 to 20.

25 years old. Therefore, the theoretical lifespan of man is the shortest.

100 years old, the oldest.

175 years old. At present, it is accepted that the ideal life expectancy of a person should be 120 years.
