I don't know about anyone else but every time I get health advice it's from an unhealthy looking person. (Wiggs not talking about you. Don't know you) I once had a guy say to me you better stop running it's bad for your knees at your age. The guys was soft, fat and couldn't run around a block without gassing. Thanks, I'll adopt your life style.
Regarding water I drink spring water from Maine. The same stuff that bears drink, wash their paws and crap in.
