Scientists say there’s a limit to the human lifespan – and we’ve already hit it
Humans may have reached their maximum limits for height, lifespan and physical performance, according to a first-of-its-kind research that looked at 120 years worth of historical information.
Scientists suggest that humans have biological limitations, and that anthropogenic impacts on the environment – including climate change – could have a deleterious effect on these limits.
Despite stories that with each generation we will live longer and longer, this review suggests there may be a maximum threshold to our biological limits that we cannot exceed.
Researchers studied trends emerging from historical records, concluding that there appears to be a plateau in the maximum biological limits for humans’ height, age and physical abilities.
“These traits no longer increase, despite further continuous nutritional, medical, and scientific progress. This suggests that modern societies have allowed our species to reach its limits. We are the first generation to become aware of this,” said Jean-Francois Toussaint from Paris Descartes University in France.
Rather than continually improving, we will see a shift in the proportion of the population reaching the previously recorded maximum limits.
Examples of the effects of these plateaus will be evidenced with increasingly less sport records being broken and more people reaching but not exceeding the present highest life expectancy.
