Seriously, everyone is talking about how near impossible it is to drink 8 cups of water a day. And I don't get it, granted, I have a reverse osmosis tap and a well of clean, high quality water at home, so I drink a lot of water. 16-17 cups a days worth, every day. And no, I do not go to the John every third minute. So how much water do you drink? is city water less refreshing after a days worth of hard work? Why is 8 cups a day so crazy?
