Humans are found to tend to be 'hard to die' beyond the age of 105, and the possibility that mankind has not yet reached the lifetime limit

By Spyros Papaspyropoulos

It is clear to everyone's eyes that all living beings, including humans, will grow older and "aging" will proceed, someday reaching a lifetime and escape from death. However, in the newly published research results, it has been revealed that aging may become progressive or stop at a certain age . In addition, the fact that the pace of aging drops after becoming older means that it is possible to think that the life expectancy of human being is even further than what was conventionally thought.

Creatures get closer to death as they grow older, the higher the age, the greater the probability of death at that age. The mortality rate of human beings at 50 years is twice that of 30 years old, and it is said that the probability doubles from 60 years old to 70 years old each time you become one year old. "The oldest dead at the time of writing" was born on February 21, 1875 · French woman Jeanne Carman of August 4, 1997, the age at the time of death is 122 years old. In other words, for human beings it can be said that "the death rate of 122 years old is 100%."

It is a natural idea to think that this mortality rate is thought to increase probability as age gets higher, but it is said that an interesting trend became clear by actually taking statistics. The research team of Elisabetta Barbi Associate Professor of Roma La Sapienza University has reported that people over the age of 105 have decreased mortality rate at that age.

The research team analyzed the data of 3836 residents who exceeded 105 years between 2009 and 2015 using demographics data recorded by the administrative agencies of Italy and calculated the mortality rate. In Italy, the data on elderly people is left in detail, so Kenneth Wutcher, a democratist at the University of California at Berkeley, said that "this is the cleanest data ever made," its high reliability I am talking about.

According to the contents released by the research team, the mortality rate at a certain age that has increased with age will rise more than 105 years of age. People who lived to 106 years of age are very likely to be able to welcome 107 without fail, and it is also clear that the likelihood of a 111-year-old person not reaching 112 years will not decline as well. About this result, Yoop De Beer, a democratist at the Netherlands Interdisciplinary Demographic Institute in the Netherlands (Netherlands Interdisciplinary Demographic Institute), who is not engaged in research, said, "A reasonable pattern of good data is shown I am doing it.

Research team Watcher further said, "If there is an upper limit on the lifespan of human beings, this result will be the evidence that we have not reached that limit yet," said Watcher from the statistical data It shows a way of thinking that human beings will still be able to live longer.

However, on the other hand, it seems necessary to pay attention to the fact that there are scientists who point out that the quality of data remains questionable. Mr. Leonid Gabrirov, a biological demographer at the University of Chicago, says that it is necessary to add to the inhabitants that were not included in the surveyed data over 3,800 people. The reasons for the existence of residents not included in the data are "I could not confirm my birthday and I could not grasp the correct age", and by including such residents in the overall data, It is necessary to consider whether the influence will come.

This decrease in mortality rate is a phenomenon called "mortality plateaus" that has been clarified to be found in small animals such as Kobae and the like from previous research, and whether the same phenomenon applies to humans Has become a subject of debate. Mr. Gabrirof says, "This result will not converge the argument of mortality plateaus, but rather will accelerate it."
