Fitness and sweat

[ny biker]

I've heard the maxim many times that if you don't have to pee every hour, you're dehydrated. But I don't know whether that's an urban legend or really has scientific support. It makes sense that if you're not peeing, your kidneys aren't detoxifying your body the way they're supposed to.

I don't worry about frequency so much as color, although I think they tend to go together. As long as it's pale, I figure I'm okay.
