Let me put it this way. Compared to you guys and gets & ladies here,... I stink. Once a day every day wow! it's only once a week for me... sometimes more >

. I do wash hands and face everyday though and I don't really do sports or anything like that, I don't really sweat, not even on hot summer days.
EDIT: Ow, and a chemistry teacher of mine once told me about certain bad repercussions to your hair if you shampoo it everyday. I would suggest against it myself. I can't remember the details, but you have internets for that. And if you guys shower everyday you shouldn't need to use soap on your bodies all that often, it's best to use just water every 2 days or so.
