That formula for water is way too extravagant. I basically don't drink water at all. If I were to follow your 'rule' I would be imbibing 70 oz of water per day. I could swim in that amount. These people who walk around with water bottles and who can't seem to make it to the end of their driveways without a canteen astound me. This is a fairly recent phenomenon, all this water drinking. If you aren't thirsty why drink? Surely the body can tell us if it needs moisture. My stomach sure as hell lets me know when it is empty or my bladder when it is full or my skin if there is something pricking it. Drinking so much water has to raise hell with the kidneys.
