I WONDER - How Much Hair Do Humans Have?

The video explains that only 5% of the human body is hairless, specifically the lips, palms, and soles. Humans have the same number of hair follicles as chimpanzees, but human hair is less thick and dark. Hair is a defining characteristic of mammals, with only a few species like elephants and whales being nearly hairless.
