What is the maximum lifespan of a human being and how many years is the lifespan of a human being?

There is no upper limit to human lifespan Researchers believe that the maximum lifespan of humans is currently steadily increasing, and there is no certain limit. Previously, scientists believed that the limit of human life was 120 years old, and no one could go beyond this limit. However, American researchers believe that the fact that the oldest people are living longer can suggest that there may be no upper limit to the lifespan of humans.

Researchers from the University of California in the United States have analysed births and deaths in Sweden over the past 240 years. Sweden has a well-established longevity record and is considered a quintessential industrialized country. The researchers found that the age of the oldest surviving birthday star showed an upward trend.

For example, the oldest birthday born in 1756 and died in 1857 is 101 years old, while the oldest birthday born in 1884 and died in 1993 is 109 years old. The oldest birthday boy died at the age of 101 in the 60s of the 19th century, and this record slowly rose to 105 years old by the 60s of the 20th century. But in the 40 years since, this record has risen rapidly, reaching 108 years by the 90s of the 20th century.

Wilmouth, a professor at the University of California, pointed out that improved sanitation, improved public health, and increased water security have contributed to the extension of human lifespan. Today's elderly people are not as frail as children of previous generations as they were in childhood, he said, and this change occurred 80-100 years ago. After 1970, the trend towards longer life expectancy began to accelerate.

This is inextricably linked to breakthroughs in certain medical practices, such as the understanding of heart disease and stroke. Professor Wilmouth refuted previous theories that humans could not live longer than 120 years. He said there was no scientific basis for estimating a definite upper limit of life.

Whether it's 115 or 120 years old, it's some scientists who are using chemistry to spread it. Wilmouth noted that research shows that the maximum lifespan of humans is changing. Lifespan is not a constant in physiology, and it is difficult to say whether it can be extended indefinitely, and there is no indication that the trend of longevity is slowing down.

It is a fact that human beings take from variables and progress. In the river of time, human beings are constantly breaking the boundaries of life.

Biologically, there is a formula for calculating the physiological lifespan of mammals: physiological lifespan = 5 7 times the growth period.

A person's growth period is usually expressed by the time when the last tooth erupted, which is about 20 to 25 years old. In this way, the ultimate life expectancy of people is more than 100 years. A previous study in the Netherlands also showed that the ultimate life expectancy of people is about 115 years.

The oldest human being on the current world record is a French woman, Jeanne Louise Calment, who lived to be 122 years old, was born in 1875 and died in 1997.

As for the 800-year-old Peng Zu ......I always believed that this was just a legend.

Although there are not many centenarians everywhere, if you look back at the history of human development, you will find that the life expectancy of people is indeed increasing.

In ancient times, 70 years old was considered a high life expectancy, but today there are more than 100 countries around the world that have reached the average life expectancy of 70 years or more, and the 2016 survey report shows that the average life expectancy in Japan has reached the age of life.

The increase in life expectancy is due to the rapid development of economy and science and technology, the progress of medical technology and the reduction of wars.

However, it is important to be clear that it is impossible for a person to live forever.

Eternal life is a beautiful vision, ancient emperors will be hard to pursue, now there are scientists dedicated to research, but after all, they must bow their heads in front of the natural laws of birth, old age, sickness and death.

After all, for people, cells are king, cells want people to die, people have to die.

The average life expectancy of human beings is 70-80 years, but the average life expectancy of human beings has changed a lot compared with before, and it has been extended because of the good quality of life and sanitary conditions.

After the extinction of the dinosaurs, it took almost more than 50 million years for humans to appear, and the extinction of the dinosaurs was probably more than 65 million years ago when humans appeared, starting from the ancestors of humansProbablyMore than 10,000 years ago, there was a difference of nearly 6,000 in the middleTen thousand years, it is almost proven that there can only be one creature on the earth that is at the top of the pyramid. <>

According to our recent dinosaur era, dinosaurs have lived on the earth much longer than humans, about 30 times more than humans, because humans have existed on the earth for only about 5 million years, dinosaurs have existed on the earth for 180 million years, and after the extinction of dinosaurs, human ancestors appeared after more than 50 million years, and then we continued to evolve, about 2 million years ago, and gradually had this model of modern manLet people's wisdom really develop, to develop production and life, and have their own civilization, then the days will be much longer. <>

The earth is such an environment, it can provide limited resources, it can only let a creature at the top of the pyramid, we observe the shape of the pyramid, in fact, it is similar to the biosphere, the lower the more types of organisms, the higher the species of organisms, we can also understand that a company in the company can only exist one chairman, the rest of the people can only play an auxiliary role, because there must be a person to occupy the main resources, master the main decision-making power, This group can be developedThe Earth's control over living things is actually the same, and only one creature at the top of the pyramid can keep the environment in a more balanced and stable state. <>

Dinosaurs can exist on the earth for so long, because dinosaurs only need some resources on the surface of the earth, it will not feel that it is the resources inside the earth, although human civilization has not existed for a long time, but we have developed a variety of technologies, we are constantly hollowing out the earth,The development of our economy needs the support of traditional energy sources, such as coal, oil, and natural gas, which are grabbing the earth's resources, so it is unknown how long human beings can exist.

At present, there are no accurate statistics on the average life expectancy of all human beings, but it is estimated that the average life expectancy of human beings is now under 70 years old. Here's the latest on the average life expectancy of humans**.

At present, the average life expectancy of Chinese is 72 years old, and based on this, the following questions are added and subtracted, and finally your possible life expectancy can be obtained.

If you are male, minus 3 years old; For women, it is 1 year old.

Xinhuanet Los Angeles, March 4.

According to a recent study by American researchers, the average life expectancy of human beings will not exceed 85 years in this century, even if medicine is developed.

At an interdisciplinary scientific conference in San Francisco, the researchers said there was no scientific basis for the idea that the average human life expectancy would be 100 to 120 years. Even if doctors can control mortal enemies such as cancer, heart disease, and stroke, the average human life expectancy can increase by up to 15 years, mainly because human Yechang cells have a limited lifespan, and there are no genes in humans that can be activated to prolong life.

According to researchers.

According to Heflick, the structure of human beings determines that people can only live for a few decades, and some people can live longer than the average person.

Forty or fifty years is a gift from God.

However, the Danish University of Kari. Christensen noted that in Scandinavia.

The number of people aged 100 years or more is increasing exponentially every year. In addition, the longevity of Japanese women has always been indisputable. The mortality rate of Japanese women is decreasing at a rate of each year, while the mortality rate in France and the United States is decreasing at a rate of and, respectively.

Jay of the University of Illinois at Chicago. Orshasky is convinced that neither hormones, antioxidants, nor genetic control, nor biochemical processes, is a magic wand that can prolong human lifespan. Since the beginning of the 20th century, the life expectancy of people in industrialized developed countries has been extended by 30 years, and it is unlikely that there will be any significant increase in human life expectancy in the foreseeable future.
