Tsk. Such a thorough answer. Yes, I know that it's clear when one is not dehydrated. And what does that indicate? It indicates that most of the North American populace IS dehydrated most of the time. People generally do not drink enough water. Instead they drink coffee, tea, soft drinks, and other stuff like that, most of which dehydrates them further.

Urine can also turn reddish when you eat beats. This can come as quite a shock to some people, if they haven't eaten beets before...or in a long time.
