A new study calling into question the limits of human life

Gian Luis Caliment lived 122 years and 164 days, the longest documented life of all time.

His interviews illustrate an example of the high spirit of over 100 years: "I do not have any wrinkles, only one, on which I now sit," I declared to journalists at the age of 110 years.

Calmant died in 1997 in Arles, France, where she spent most of her life.

According to precise records, no one has lived more than 120 years.

That the human age is a secular question, statistical expert Benjamin Gompertz suggested in 1825 that mortality rates accelerate with age.

Under the Gombertz Act, the probability of death is reduced every eight years.

This may seem like a law for people between 30 and 80 years old.

But scientists question what happens to end-of-life rates.

A new study published the week before in the journal Science showed that the mower of life suddenly reduces his speed.

Lead author of the study, Kenneth Wachter, Emeritus Professor of Demography and Statistics at the University of California at Berkeley, said: "The goal was to settle the debate on whether the mortality rate is similar to that of other species.

Mortality rates were low in laboratory animals, such as Mediterranean fruit flies and nematodes.

Kenneth said, "We think we have fixed that."

The mortality rate accelerates to the age of 80, then slows down until it stabilizes between 105 and 110 years of age and, as the authors conclude, the law Gumbertz will end in this case.

Let's be clear: we are talking about accelerating death rates, not the same possibilities.

Only 2 out of 100,000 women can live up to 110 years.

As for men, their access to this age is 2 in 1,000,000.

If you are 105, according to a new study, your probability of reaching the age of 106 is nearly 50%, the same percentage up to 107, 108, 109 and 110 years.

The researches of Elisabetta Barbi of the University of Rome Sabinza and experts of the Italian National Institute of Statistics have studied anyone born in Italy between 1896 and 1910 and having reached the 39, age 105 years.

Data included 3,836 persons, 3,373 women and 463 men.

The Italian national registry, which requires annual updates from citizens, provides more accurate data than US social security data.

"The best data we have come from Italy," says Thatcher.

Holger Rootzen of Schallmer University of Technology in Sweden considered the study to be "extremely careful and carefully analyzed" as it showed a stable probability of death between 105 and 110 years. Rotzen rejects the idea of ​​a certain reduction in human life in a December article in the newspaper Extremes, using similar information from Japan and Western countries collected by the Max Planck Institute of Demographic studies. He is 128 years old.

Two years ago, researchers at the Albert Einstein Medical University of Nature, based on data from 40 countries, reported a 115-year limit, according to the Washington Post.

According to them, Kalmant was lucky during his lifetime.

Referring to the latest research, Brandon Milholland, who worked on the study of nature as a PhD student, said that it was unlikely that the death curve would drop abruptly and from conclusively.

Milholland said that there were "more than two options".

Jan Vijg, co-author and specialist in genetics at the Albert Einstein University of Medicine, launches the choice between acute stability and the Gombertz law as "false binary branch".

"The amount of error is too great," said Mellhonwald, leaving room for sharper curves in the Italian data.

Melhonald believes that the Gombertz law should end, because mortality rates can not be weakened to more than 100%, but this study, which says mortality rates stop doubling to about 50%, n Is not convincing.

Rotzen attacked periodic discoveries (Nature) that say there is a life limit, saying that there is a statistical error.

"Yes, there is little chance of living more than 115 years, but that does not mean that there is a limit to the foundation," he said.

An example of a dart board was used, he can not hit the target in 10 shots.

Throw thousands of arrows on the board, and you can hit it.

"They do not understand this problem, if you try harder," he says, "more on the board or people who live longer", the figure will be higher.

The number of elderly people is increasing.

In Italy, for example, four people were born in 1896 and lived up to 105 years and over.

More than 600 people born in 1910 are still alive.

Between 1896 and 1910, the infant mortality rate in Italy was reduced, according to Wachter.

In recent decades, the quality of care that people received in the 1980s and 1990s has improved, resulting in an increase in the number of centipedes.

"When we understand the interaction between our genetic heritage and other well-studied factors such as nutrition and behavior, we understand why some people have reached the age of 80 and over , said Wacher.

Up to now, most of us have survived from all walks of life.

"Lifestyle recommendations: practicing, eating and not not eating are important for the younger ones, but do not seem to play a role in the more advanced ages, "said Rutzen.

Calming says she's been smoking two cigarettes a day until the # 1 39, age 119 and she quit because she did not see enough to light a cigarette
