If you suspect that the conclusion of two French scientists that physical and intellectual abilities of humans eventually follow an "irreversible negative exponential curve" is bad news, you are correct. Springer Select news service reports that Geoffroy Berthelot and Stephane Len, both researchers at the IRMES (Institut de Recherche bioMédicale et d'Epidemiologie du Sport at INSEP, Paris, France), have published their findings in AGE, the official journal of the American Aging Association, describing the evolution of performances in elite athletes and chess grandmasters. The researchers modeled the careers of more than 2,000 athletes (from a panel of 25 Olympic disciplines) and grandmasters of chess. They demonstrate a simple relation between changes in performance and the age of individuals.The study shows, for those in doubt, that the evolution of the performances of an individual throughout his life follows an exponential growth curve to a peak before declining irreversibly, following another negative exponential curve. This peak is reached at the age of 26.1 years for the disciplines studied: athletics (26.0 years), swimming (21.0 years) and chess (31.4 years).

“Uh Oh, Life = Negative Exponential Curve”
This doesn’t bother me.
I forgot the meaning of “exponential curve” decades ago.
Exponential curve is depends on the age started affects from age of 26 and goes long. . .
