lets see,first it's bowels, not vouls but I'm not a nit-picker
To poop, eat lots of tacobell and poor quality chinese food. If that doesn't make you poop then you never will.
to pee, drink water and a few 32oz soda fountain drinks.
you should eb good to go. If you want uncontrolable then take some alli, it causes anal seepage. Or you could be diabetic and take metformin, then farting becomes a game of is it or isn't it.
