Longevity: Has human life reached its biological limit?

And Did the oldest person ever die? Since 1997, when Jeanne Louise Calment, the longest living person to date, died, no one has lived past 122 years. According to many, this means that human longevity has reached a biological limit.

David McCarthy, study coordinator Posted on Plos ONE, disagrees: “There are significant generational differences that reports often don’t take into account,” he explains. According to what his studies found, in the future we will definitely be able to exceed those 122 years, because the human life limit has not yet been reached.

longer and longer. The study, which analyzed the death rate of people born between 1700 and 1969 in 19 industrialized countries, including Italy, highlighted that in those born between 1910 and 1950, the rate of increase in mortality, which usually rises with age, has already happened. It has decreased dramatically, which means that the maximum age at death will rise exponentially in the coming decades as members of this group age.

“If there is ever a limit to human lifespan, we haven’t reached it yet,” says McCarthy. According to the data, the longevity record could be broken by 2060. “In the group born between 1910 and 1950, there is a delay in mortality not seen before, but they are still too young to break longevity records,” the authors explain.

delayed deaths. The reason for this increase in longevity is not clear, but it may be attributable to it Improving public health and medical technology. In general, in groups born around 1900 there is one mortality pressure (that is, the concentration of deaths in old age) in most countries, while in those born between 1910 and 1950, the trend was towards Postponement of deathsNo increase in life expectancy.
