[Paddlewise] drinking urine???

<
I'd only heard about drinking urine anectodally.  Is it
actually a viable survival technique?  Would urine be good
for flushing out a wound? >

 Drinking urine would not be a good survival technique.  Although a well 
hydrated person may pass relatively dilute urine one under hydration 
stress they will pass ever more concentrated urine.  Drinking this would be 
one step above drinking sea water and even if you did not suffer from the 
first go around the second time or third when you were really dehydrated 
and the urine concentrated you would be in trouble.  Sterile is only half the 
point--Urine (like sweat) as other have pointed out is the result of your 
body ridding itself of water soluble metabolic toxins and breakdown 
products- to drink these again would be to drink your own toxins and may 
damage your kidneys and would require even more water to cleanse this 
new insult- this would only make a bad situation worse.  I have read of 
some people who drink their own urine regularly (for religious or other 
reasons?) but I suspect they tempor it with a healthy amount of normal 
water. 
   As for jelly fish they are Coelenterates- Portuguese Man-of-War is a little 
different it is a hydroid colony- in both cases they have a very simple nerve 
net (no brain) but they do well.  Mostly they blunder into prey but they do 
swim purposefully and are light sensitive.  As for flushing nematocyst with 
urine I don't have any information, normal urine is acidic but only barely 
so- maybe vineagar would be a better choice if available????
