  • Researchers say humanity has already reached the upper limit for longevity, which sits at about 115 years.
  • Many scientists run mathematical models predicting leaps in the lifespan of humans without considering biological and environmental factors.

There’s a limit to the human lifespan and physical abilities, and a multidisciplinary team of researchers say that we may have already reached this threshold. Sadly, it’s one that we may not be able to exceed. Indeed, signs point to a plateau in maximum genetic and biological limits for a person’s age, height, and physical capabilities.

This first-of-its-kind study, that covers over 120 years worth of historical information, was published recently in the journal Frontiers in Physiology. Instead of breaking through this threshold, there would be a shift in the proportion of people reaching the current threshold. In short, more people would be hitting the highest life expectancy but not exceeding it.

“[M]odern human potential, including an enlarged brain, adult height, lifespan, and physical performance, has been dependent on very long-term evolutionary parameters,” researchers Jean-François Toussaint and Adrien Marck from the Paris Descartes University in France told Futurism.

Furthermore, when combined with anthropogenic factors — or our effect on the environment — this threshold might even see decrease. “All human biomarkers (renal filtration, respiratory rate, lifespan, etc) depend on both genetic predispositions and environmental parameters, with risk factors possibly limiting the function/performance of each studied organ/organism,” Toussaint and Marck explained. “A positive environment further favors functional quality, while increased constraints limit it.”

The limits of longevity must take into account biology
