But this does not mean it qualifies for the recommended 6 - 8 daily glasses of H2O, and here's why: in addition to the water content, urine contains trace elements of hundreds of other things —from undigested alcohol to nitrogen and potassium, and sodium, which makes it such a salty drink. (By the way, the first pee in the morning is more concentrated; and the more water you drink, the more diluted it will be.) Urine could — in rare cases — also have some toxic substances in it, such as lead or arsenic. It can also contain trace amounts of drugs that the urinating person has recently ingested, though probably not enough to actually give the sipper any high or show up on a drug test.<br><br>Also, if a person were to drink his or her own urine as a substitute for fresh drinking water, the proportion of water content would rapidly decrease as the proportion of harmful waste products increased."DevonMon, 13 Oct 2008 10:10:16 -0000http://gcaptain.com/maritime/blog/10-things-to-remember-if-youre-shipwrecked/#comment-3021272On number 2: of course drinking urine or bird blood isn't something you would like to do, but couldn't it save your life?<br><br>@fred Does that really work, or is it a joke?MarkMon, 13 Oct 2008 09:15:12 -0000http://gcaptain.com/maritime/blog/10-things-to-remember-if-youre-shipwrecked/#comment-3021212Priceless!TomMon, 13 Oct 2008 09:10:22 -0000http://gcaptain.com/maritime/blog/10-things-to-remember-if-youre-shipwrecked/#comment-1341761@ Point 4: paralysis is a noun, try paralyse (or paralyze if you prefer American English)nikolieriSun, 06 Apr 2008 20:21:01 -0000http://gcaptain.com/maritime/blog/10-things-to-remember-if-youre-shipwrecked/#comment-1341760My foot is a horrible judge of lots of stuff.
