Jack was an eccentric inspirational man. The world needs people like this. Eccentric to me is a term of endearment. So what if he wasn’t perfect in his exercise & nutritional advice, being ahead of his time in many things he was ahead of general scientific proof in these areas. He only said things he knew to be true by experience and was living proof of the success of what he said. I’m glad he lived a long life & remained happily active all of it. I go with his view that a joyously active life is good no matter what its length.
