Geez How fit is this guy, at 90 something and he is as fit as a mully bull, i never heard of him either until i read the interview, what an amazing man.
My very first employer of whom i stayed friends with, is now 95, he only looks around low 70's, and still sharp as a razor, he eats a LOT of fish, not much red meat at all, so there might be something in this eating lots of fish is good for you, after all ???
