>>11918835>>11918815Humanity has always favored genes that makes people strong and beautiful in their late teens to their late 20s because humans (in average) didn't start living past that age since couple of years ago compared to the time we have been living.
Think about it, there is no cons on having shit genes for old age if you don't live to see it, and since that's the case for ancient people, genes that give away good traits for old age for good traits in one's younger life thrive more. And genes that made us age like shit snuk into our species because it didn't matter.
