Thanks Bob I live on the top of a hill, nearly a mile from work, and I walk that at least a full loop everyday, to and from work, considerably further if I have to take my kid to Taekwando or have other chores to run. I'm not disputing the health benefits of walking, I'm just saying that you don't need to go to the gym and get your spandex on to walk a few miles.
