Not sure that holds up to strict scrutiny. It's a fine hypothesis for the armpit but makes no sense with the groin. There the hair is heaviest on skin that touches nothing else and almost indistinguishable from background on the actual sliding surfaces. Same for butt crack.
- dvh 4y agoHair act as mechanical lubricant.
- causi 4y agoExactly, so why isn't there more hair on places that need mechanical lubrication other than the armpits?
- dvh 4y agoWhat places?
- causi 4y agoThe creases between the tops of the thighs and the abdomen, the crease between the butt cheeks.
- dvh 4y agoThe angle would not be right, you want hair growing slightly off an roll parallel where it should lubricate. Armpit is bit of problem because it normally goes 180 deg so they cannot choose preferential direction. There the optimum is probably more radial then linear.
