Jack LaLanne, at 92, is still probably in better shape than I am. I had no idea he was still alive, in fact, but he is, and kicking.
I remember his show from my youth (both then then-current color editions and the black-and-white reruns). When I think of physical fitness, I think of Jack. Not that I could ever follow the regimen he does — but he’s a guy I admire terribly for it.
