So most agree that there is no healthiest environment/habitat and that we are naturally nomadic and this allowed us to become who we are today? Is it possible that each specific individual is best suited for a specific location? Instead of me implying that the entire human species is best suited for one place.
just had a random thought though
The ability to use shelter protects us from predators, weather, keeps us safe, and allows us to sleep better because of the absence of noise and the fear of predators at night.... Then this in a sense alleviates stress which would allow us to be healthier and live longer..
