[He-Man] Why don't most of the Males wear shirts?

Surface area to volume determines how well something can radiate away heat. Skinny people lose heat faster because they have relatively high surface area for their volume. However, volume increases at a cubic rate, and surface area increases at a square rate. The men of Eternia have very high chest volume and not enough surface area. Wearing shirts could be enough to cause them to overheat.
