How long can a human live at most? How long do humans really live?

Indefinite, after the long human age back to the positive.

There is no upper limit to 120 human lifespans.

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.

Not necessarily, some people die before they are born, and some people live to be more than 100 years old, depending on how you take care of yourself.
