LOL! I bet he could do it, too! When I saw Jack in a tv commercial last year I googled him and learned that he turned 93 last year (2007) and that he is still going strong. I found a website of his that had some really cool photos of him from the 1940's. Wow, he was in shape. Some of the "feats of strength" publicity stunts he did and the records he holds for his age group are pretty impressive.
I remember watching his show on tv when I was a kid. I really liked his white German Shepard, Happy. Jack is an American treasure, that's for sure.
You can get his old shows on DVD. Mrs WBill worships at the temple of Jack Lalanne. He used to be on ESPN2 at about 6am...not sure if he still is.
He was doing excellent low-impact, aerobic exercise, before it was called 'low-impact aerobics'.
