Can people extend life expectancy in the future?

Human lifespan never lasts forever, unless there is a breakthrough that can handle all age-related health problems.

That was the result of a new study published in the journal Nature on October 5.

Currently, the title of the oldest person in the world officially belongs to Jeanne Calment, a French woman who died in 1997, enjoying the life of 122 years old, and this achievement will most likely not be broken.

"It seems that breaking that limit is extremely difficult if not impossible, due to the complexity of the aging process," said one of the researchers, Jan Vijg, a geneticist at Albert Einstein Medical University in New York said via email.

"Contrary to previous suggestions that human life expectancy can be further extended, our data clearly shows that the length of human life is limited, " researchers said. said.

The likelihood of someone reaching 125 years of age is 1 / 10,000.

In this new study, the researchers analyzed data on death rates from a global database.

They found that although progress has been made in reducing deaths in young children, women in childbirth and the elderly, the rate of improvement is slower for very old people, that is, people over 100 years old.

Scientists have focused on deaths between 1968 and 2006 in France, Japan, Britain and the US - which are four countries with the highest number of people living on 110 years, according to the International Database of life expectancy.

Researchers have calculated the possibility that someone reaching 125 years of age is 1 / 10,000, and they think that the life expectancy of people is more likely to reach only 115 years.

However, the new findings do not mean that researchers know for sure that humans will never live more than 122 years, which is the remark of Steven Austad, a University of Alabama biology and aging professor. in Birmingham, who did not participate in the study.

Professor Austad said that human lifespan is likely to be extended. Professor said the experiments on mice have shown that these animals can live longer if their calorie consumption is limited or if their genes are altered.

Austad said if researchers found drugs or lifestyle factors, such as special diets, better than today's known diets, that would can allow people to live longer.

Dr. Thomas Perls, a professor of aging at Boston University, said that instead of finding a miraculous cure, people should focus on eating healthier and practicing to stay healthy.
