When you're doing serious athletics, of course, your sweat is a very significant
output of water. Back when I would do two hours of aerobics in a row, I would
often drink 3 L over that time, and still be a bit thirsty. I think probably one's
own body won't mislead one into drinking too much, but I agree that caution
is prudent when doing our little chug-a-thons.
