i remember when i was in the army, some bully peed on my feet when i was in the shower, and since he was built like ali i wasn't going to do anything but move away from him. but i got back at him a while later, by telling him that scented bath powder [corn starch] would make a great deodorant "down there," so after his next shower, i spied him out of the corner of my eye, corn-starching his package as he was dolling himself up for his date, and i laughed up my sleeve at him. for those who don't get my meaning, if you put cornstarch in places like feet and privates, it ferments in the heat and moisture/sweat of those places and stinks up a storm. i found that out myself, the hard way.
i tried talcum powder also, but that caked on my feet and chafed "down there" also, so i just gave it up and decided instead to bathe twice daily in hot weather. i also tried cornstarch on my neck as a shaving lubricant, but it only made my neck stink when it got hot. talcum powder is a no-no for shaving because it eats up the [electric] shaver blades. i would like to discover other uses for talcum though.
