> elderly are not going to be walking to the grocery store. This is by design. That's it. There's nothing stopping elderly people from walking to grocery stores except that we build in a way to make that impossible. They'd probably live longer and be healthier (as we all would be) if we walked a little more. It's very easy to test this - how do most people in the world including the elderly get their groceries? > I should add that even if we all agreed to turn back that dial I wouldn't be so quick to suggest that walking is turning back the dial anymore than stopping smoking is.
