I've heard of people doing this kind of thing. Can't understand it myself, I was under the impression that urine was waste products, so I fail to
see how ingesting it be beneficial? Besides -
Although it does make for the funniest stories.
Long story short:
A good friend of mine, Locozade addict, always leaving half finished bottles lying in the car. Family outing with their little boy who needs to do
what little boys do, in the middle of nowhere, mother sorts it out.
Early next morning, friend still sleepy, half filled Lucozade bottle. Lots of tooth brushing. Me laughing for about six months.
Ahh

it still gets me, I'll have to show him this thread.
Anyway, I think Rolf Harris does it, and after his cover of Stairway to Heaven I am convinced he is the Devil, so it can't be good.
