Has the life span of mankind now reached its limit? A study of Italian centenarians may not have arrived today because it found that life expectancy is slowly rising.
Scientists have long debated whether human life has reached its maximum. In 1997, a French woman, Calmante (Jeanne Calmant), died at a record age of 122years, according to a 2016 study in the journal (Nature), the journal of science. Human life has reached its limit.
But a new study in the journal Science (Science) points to the possibility of longer life expectancy, which may continue to increase over time.
According to data from more than 3800 Italian centenarians, the researchers found that the risk of death after reaching the age of 105 decreased or even stabilized.
Wachter (Kenneth Wachter), co-author of the study and professor of statistics at the University of California, Berkeley, said: "as we get older, our health and death risks deteriorate faster and faster, but at extreme age they stop getting worse."
"they won't get better, but they won't get worse," he told AFP. They tend to be smooth, which is called a stationary period. "
The researchers studied 3836 cases of Italian residents over the age of 105 born between 1896 and 1910 between 2009 and 2015.
Wachter said: "over time, the stability we see over 105 is slow but significant, giving us the hope that what we see now may not be a fixed limit of human life."
