Did you hear the urine therapy?  Believe it or not, it is big business these days and there's an annual market of US$500 million for products made from urine. There are many applications. For example, some consumers think it's a great aftershave. And in some case, it's used as in many skin creams and perfumes. But more incredibly, it's even used as a kind of medicine. A lady in American says she drinks a glass of urine a day. 

Although it does really some work, I still don't accept this way.
