From the International Business Times:
Humans won’t get any better than they are right now, scientists say. In fact, we can expect to become less healthy and live shorter lives in the future.
Although people have made great biological strides in recent centuries, including increasing lifespans, there has been a great slowdown of those improvements, a group of experts wrote in an article for the journal Frontiers in Physiology. They say that’s because our species has reached its peak and will only trend downward from here. And climate change may help drive that dive. The team analyzed genetic and environmental factors to investigate the biological limits of humans, in the realm of longevity, height and physical abilities like performance in sports. In terms of lifespan, for example, medical and technological advancements have pushed the average life expectancy close to 100 and the maximum a couple of decades beyond that. But how much further could we reasonably go?
