ELI5 : Why aren't we hibernating in winter like most of other mammals ?
gpt
Humans evolved in a tropical part of Africa, and are adapted for existing in that sort of environment. We can adapt ourselves to live in colder environments, but have to provide shelter and clothing to survive there. You can live naked in the jungle with very few tools--ask any of the tribes all around the world who pretty much live that way. For the same reason, we're never going to be able to hibernate, we simply did not evolve that way.
