Why do you urinate repeatedly when you drink deeply of river?
Because all that hose down is clearing your system out and most of it just go through your body and not much will be absorbed because in that your body needs some, but at hand isn't any vitmains or minerals it's getting so it goes straight to your bladder.
A lot of marine is eliminated through your skin as perspiration but hose is also a diuretic and excess water that your body can't use have to be eliminated.
