Drinking your own urine!
Personally I really don’t see how this is good for you. Or indeed why anyone accepts it when they’re told this ‘fact’. Surely by the logic of ‘drink your own piss it’s good for you’ One could assume that eating your own shit is also a great way to improve your health. I’m almost 100% sure that you can get very nasty things happen to you if you eat your own shit. So I’m not going to fall for it!

It does however make me wonder how or even why people discovered that drinking your own piss is ‘good for you’. In some ways I like to think that perhaps in olden days a grumpy servant pissed in the kings wine every day. One day he got found out and put to death. Unfortunately soon after the kings health deteriorated and he died. People realised that drinking piss was a good thing.
There is of course a flaw in this flight of fancy. Is it still good for you if you drink other people’s piss? Perhaps there’s something different about your own. If you could drink others, then why don’t health food shops have high quality athletes piss on sale. You could even have different flavours: “Dislike the tangy aftertaste of quality piss? Try new cranberry flavoured piss, for the discerning debutant”.

In shot, I find it hard to believe, the possibility that piss is good for you is probably very reliant on the concentration of urea and other wastes. Even then I think it’s a bit of a wild statement.
