In times of disasters like earthquake, urine can actually save
your life. I read it in a chemistry science magazine.
Its a form of water IF you are desperate but not for casual
drinking or long term. Just like when people have no food, some
will eat grass etc just to get some 'food' into the stomach, same
logic.
Those who promote drinking urine as a form of therapy is just
crapping and have no proper scientific proof.
