Microsoft adCenter Labs has a demographics prediction engine. Based on a person's search queries and web sites visited, it can predict their gender and age.

So I tried that on parts of the body, to see what men were interested in vs women.

While I can understand men being more interested in beards and moustaches (perhaps even legs), why are they far more interested in toes than women?
