As we can see, and even studies reveal, the population is aging. The life expectancy of people generally increases, in the big part of the world, so, this is not really something extraordinary these days, we find people living more than 100 years.
The novelty is that, according to a study by University of Rome La Sapienza and published by the journal "Science" this week, human aging has a limit. Researchers say that when a person reaches the age of 105, aging is stopped. “/> the 100 years.

All of this happens because the risk of impending death is already something natural for people in this age group. To conclude, when someone exceeds 105 years, it is virtually impossible to predict how long it will last.
"If there is a biological limit to human life, it has not yet been verified," said coordinator of the study Elisabetta Barbi, at ANSA [19659002] Researchers also said that age influences the risk of death. In a study with insects brought quite interesting data. The authors sought a response to the fact that there may be a limit to aging
"This not only gives a clear and certain answer on mortality rates, but is crucial to understanding the mechanisms on the basis of human longevity, and for the future development of aging theories, "Barbi said.
But not all researchers support Barbi's study. Jay Olshansky, a professor at the School of Public Health at the University of Illinois, said the data obtained by the new study are well detailed, but there are still problems as few reach this age.
"There are not enough survivors after 110 years to generate reliable mortality rates.Remember, these few people of this age have been highly selected in time, so the only ones who can live so long have had to win the genetic lottery at birth. "
Really, more than 100 is for the few, In countries like Japan, where life expectancy is high, this n & # 39; It is not so rare.
