7-8 litres of water?
7-8 litres per day?
Isn't that a tad much?
I would say so. That's about 2 gallons per day, probably 17 pounds worth of water per day! I've seen even the most hardcore of athletes who would brag about how much water they drink only drinks 1.5 gallons on a regular basis. There's no reason for a normal person to drink that much. I try to drink a gallon but that's probably pushing it just a little. I only do that because I ride bikes so much.
