I pee in my bath water. My granny told me about 30 years ago that it is good for your skin, so I have done this ever since.
I'm still waiting to find out if it is true.

I don't pee in my bath water, but I have been known to pee in Public pools. I'm pretty sure others do also, cause you can tell by the big grin on their faces. If it's true thats it's good for your skin, then many people benefit from it! But I got banned once from my favoriate pool, cause I peed in the pool, they said it was cause I was on the diving board at the time!

(before I get clobbered, Only kidding)
