[veascdid] Obesity, sweating, and the nudity taboo

Exercising causes the body to heat up.  To get rid of excessive heat through perspiration, one needs to have exposed skin.  People suffering from social pressures not to expose skin (e.g., poor self image) will find exercise uncomfortable.

Gaining weight leads to poor self image ("I wish I could unsee that nearly naked fat person") which thus leads to exercising less.  This feedback cycle could explain obesity.

Fat people must especially expose a lot of skin because the heat they produce is proportional to the cube of their linear dimension, but their skin surface area is proportional only to the square. Getting rid of heat is already difficult enough even without social pressures not to expose skin.

Correlate obesity with social pressures not to expose skin.
