t-shirts and shirts = 1 day (t-shirts maybe two if it doesnt smell too bad)
pants and jeans = a week if i havnt spilled or messed anything on it.
socks = 1 day i dont care if they still smell ok...thats just nasty.
undies = change every time i bath (that is even if i bath twice in one day...a new pair of undies is always needed and they have to be ironed. there's nothing like getting into a fresh smelling, ironed pair of undies
)
the whole toothbrush thing, i rinse too before i brush...you never know what crawled over it during the night. and i really dont see what's so wrong with brushing your teeth at work ngdawg...i would if i could.
