I think this "drinking urine" bullshit is an urban legend that started in the military in a war when soldiers in Vietnam use to urinate on fellow soldiers' wounds to sterilize the wounds. Some soldiers thought of drinking their own urine during battle when they had no water supply or collecting their urine to sterilize wounds when they had no medic. My old man told me about it as a joke but then I read about it in my great grandfather's war diary when he fought in World War I while enduring the 1918 Influenza Pandemic at the same time. It was preached again in World War II by some crazy British naturopath in England in which their military soldiers took very seriously by included "urine drinking" as part of survival skills during war. wrbtrader
Apparently urine is a commodity now, for the manufacture of DEF for diesel engines, and for the manufacture of fertilizer.
You mean all that urine I had collect and drink in sniper school was... Those mo-fos! (just had to make a solar still, no urine cocktails).
