I found this article online, and I thought it was interesting... http://www.eurekalert.org/pub_releases/2002-08/dms-al080802.php This doctor claims "8 glasses of 8 oz." water/day is exaggerated and false. I frequently drink large amounts of water, especially during workouts, because I'm paranoid and it's supposed to be healthy. I also do this so I'm at my "best" and dehydration is not a factor. I think what he says makes sense... do you ever really consider the water contained in an apple, for instance?
