Gender confusion...

Okay, my daughter has been SO confused when they've had Olympic swimming on. She's getting confused as to what gender the swimmers are. Typically, we see guys in swim trunks and the gals in bikinis or bathing suits. But at the Olympics, the guys are wearing those body suits that go up all the way up their shoulders. PLUS, everyone is either bald OR wearing a swim cap with their goggles. They usually only show the swimming either full body from far away or from the shoulders up. So when we've been watching she asks "Mom, is that a boy or a girl?"
