Unresolved mystery of human life span limit, science is doubtful about the age limit of human life span we have yet been considering, while a death risk of a person decelerates and sometimes even plateaus beyond 105 years. The new research disclosed in Science journal challenges all the earlier thoughts suggesting there is a point of age limit that humans cannot extend.
According to senior author of the study and professor of statistics and demography, Kenneth Wachter from the University of California in Berkeley, the pioneers of longevity quite fortunate to make it past the precarious turns of their life during age of 70s, 80s and 90s, as they could live as long as at least age 110, if luck remains on their side.
After crossing age of 105 years, the risk of mortality reduces; likewise no upper limit ever exists for the life span of humans. Benjamin Gompertz, British statistician and mathematician in 1825, observed a weird idiosyncrasy about maturity and mortality of humans. As older as a person ages, the more exponentially the death risk increases.
This theory is now referred by scientists as the ‘Gompertz Law of Mortality’. an aging researcher, Brandon Milholland from the Department of Genetics at Albert Einstein College of Medicine said in a statement that, “It’s based on seven years of data in one country, and most of the data applies for ages 105 to 108. I would say this paper does not tell us much, if anything, about supercentenarian mortality. It is also questionable if the results are generalizable to other countries.”
“This paper makes sense in that the doubling cannot continue indefinitely,” Milholland added. “If mortality is at 60 percent, it cannot eventually double to 120 percent—that is mathematically impossible.”
