>>Wow, I never thought I'd be put on the defensive about not peeing in the shower. Tell me, do you also sh*t in the shower?<<
There are actually people who drink their own pee (for medicinal purposes) with no ill effects. Eating your own poop is NEVER a good thing. Lot's of really bad stuff there!
Pee is quite sterile - at first. It's not the disgusting thing one would think at first glance. Check out the threads on military rations hydrated by pee.
Okay, since you brought it up. We have all been told that if you are lost in the woods and something needs to be flushed out of your eye, urine is the best thing.
Now to get personal, I come from a long line of country folk. My great grandmother (as well as everyone else at the time) used a few drops of urine for earaches.
Pee has been used as antiseptic on wounds if I'm not mistaken.
