Northern temperatures are low, so people tend to have higher nose bridges; southern humidity levels cause nose bridges to be shorter. One reason is for easier breathing, and the other is to prevent excessive moisture from entering the lungs. I can understand that. But why do people in the north also have prominent pubic bones? This has nothing to do with temperature. The picture is from another forum. I found it strange, so I posted it here. It's a real woman, not someone who's had cosmetic surgery.
