Gold Bond Powder....there used to be this old guy at my gym...he was in his 80's. Bless his heart. He would take a shower then stand in the dressing area, naked, and douse himself in that stuff. There would be a heavy white powder ring on the floor with the outline of his feet in the middle. You could walk in the front door and tell by the smell if he had been there.

He finally got kicked out - I don't mind telling you I was one of the complainers - because he would go in the sauna in his underwear, get soaking wet with sweat, then get out and stretch his undies over the hand air dryer and for the next 15 minutes keep hitting the button until they were dry.
