What do the
Men: Tend to be medium height with wide shoulders and thick chests. Their torsos are on the shorter side and they have very long, thin arms and legs, down to their fingers and toes. They have heavy beards the same color as their head. Men are hairy all over, arms, legs, hands, and back.
Women: Tend to be curvy with the golden proportions very common. When women are heavier they tend to get bustier first. They too have long, thin limbs and extremities. Their hair is surprisingly thin compared to the men. There is really no sign of body hair anywhere but their heads and there it is very light and thin. Women are actually more likely to go bald then men.
