Outback / Drinking Urine ==

Once again, Bear teaches people how to get themselves killed.  As Wikipedia's own article on dehydration and the article on human urine notes, drinking urine, like drinking saltwater, does nothing at best, and increases the rate of dehydration at worst.  Normal urine contains about 95% water and 5% dissolved solids, much of which is salts.  The more dehydrated you are, the higher the percentage of salt in the urine.  Your body is only about 1% salt.  Water follows a diffusion gradient, so water *leaves* your cells to dilute the urine.  The kidneys can pump ions out of your blood to try and lower the salt concentration, but not *that* effectively.  Just like drinking seawater to survive is stupid and nearly universally recommended against, you shouldn't survive on urine, either.  And here, we're just talking about the salt, let alone the ammonia, nitrates, aldehydes, and other toxins that your body is trying to get rid of.  And all of this assumes that it doesn't make you vomit outright and lose even more water.

To viewers of the show: don't do it! 

Of course, we're not allowed to mention anything except for the press release blurbs on the article itself.  P
