Why don't astronauts drink their own piss?
Isn't urine-drinking a daily ritual for, like, 20 million people across the globe? I happen to know of a friend who doesn't spill a drop... he's also into wine-nasal-imbibing, but I won't get into that here.
Why not get the astronauts to routinely drink whatever comes out of their astro-willy/pussy? Its entirely safe - as long as it isn't your only source of water as the urea concentrations start to get too high and your kidneys would pack in. But normal urine is fine - perhaps a little salty, but certainly not life-threatening. In fact, it even has antiseptic qualities. According to those in the know, its also a very good way of regulating your water intake. If you're urine is too salty - you know you need to take on more of that fresh, lovely H20.
