Seems my post was cropped. I'll try it again. hopefully I'm not triggering the foul language detectors or violating proper decorum. I figure it is pee. Everyone does it every day. Nothing to get grossed out about.

Urine, as distasteful as it may be, has quite a few 'survival' uses. As a material it isn't all that bad. Assuming you don't have a kidney or bladder infection urine is sterile. It is a natural mild astringent and antibacterial or bacteriostatic agent.

It, obviously, comes out warm. It is readily and regularly available in fairly large supplies.

Medical uses:
A pretty well known use is to use it on your own blisters and other raw, debarked, skin. The uric acid and ammonia cause the tender exposed tissue to skin over and to stop stinging and burning.

A related use is to keep intestines or other vital tissues wet so they don't die. Normal saline is generally preferred but given a lack of clean water or other options and exposed intestines that will soon dry out and die urine has long been seen as one of the better options.

Several African tribes that lived in arid areas use urine for washing wounds and to treat fungal and other infections. Seems to work. Urinating on your feet and allowing the urine to dry on them several times a day is sometimes offered as a treatment for athletes foot. Seemed to work and it is both cheap and uses a readily available material.

Mechanics:
Urine was used in Korea to unfreeze various weapons and mechanisms in a pinch. Trick is you have to immediately use it to keep it warm and prevent it from refreezing and to dry it so it doesn't lock up tighter than ever.

Urine was sometimes used to chemically treat some types of metals.

Firefighting:
You can put out a fire with it. It does cause a significant smell.

Tanning:
Urine was sometimes stored by Amer-Indians and used to tan leather.

Gunpowder:
Urine was stored in the south during the Civil War and potassium nitrate extracted and used to make gunpowder. Urine is more productive than manure.
