actually humans are evolving in the "wrong' direction: weakening in physique

losing hairs in bodies, decreasing fertility, as more and more people preferring white collar jobs, the exercise of body is less and less.

usually a species focus on producing as many progenies as possible, but we are exception. we want to live longer and have at most 2 kids ( i bet 95% middle class parents think this way).

recent articles i read about aging discussed this paradox: species' instinct of making more descedents interfere with their life span. so now if we want to live longer, we have to evolve in the opposite direction.
