All
pee bubbles to some extent, though a high
glucose level in
urine (as is associated with
diabetes) should make urine much bubblier.
Tasting urine in order to test for this glucose content (as formerly mentioned above) is probably not everyone's
cup of pee, but if you do notice a
fruity smell (sometimes described as similar to that of
mango or
papaya) in addition to a high bubble concentration in your pee, you may very well be
diabetic, and should see a
doctor.
Again,
drinking urine is not really
recommended, though it is indeed supposed to be
sterile (assuming you don't leave it lying around for long before-hand), and is consumed in quantities by
yogis and
perverts alike. It does, however, reintroduce
urea and other waste products into your
bloodstream, which rather defeats the point of
peeing in the first place. Drink too much, and you should theoretically come down with a potentially harmful case of
jaundice. Also, your
friends would begin to worry about you, and they would have very good resaon to do so. Unless, of course, they too borrow from the proud tradition of
yoga. Or that of
perversion.
Foamy pee is additionally rather something of a curse to anyone with a
compulsive streak. You simply cannot pee it away.
