I've seen so many opinions on this:
A) yes, drink it
B) no, never drink it
C) drink it only if it is clear

I really don't know what to think to be honest. I guess I'd go with option "C" if I'm really in desperate straights (and have a way to capture it).

In the army, they taught us that urine can be imbibed twice before it becomes toxic. Of course, that was in 1983, so that tidbit could be quite out of date.

I understand that urine is sterile as it comes out of the body, so it's not a source of disease unless it's been sitting or has become chemically toxic.
