Still, what is so wrong with a films starring someone of his age playing an older character? Aging is a natural part of life (pun intended). We would assume that Indy would have gotten older, and we know that he does, as seen in the Young Indy Chronicles, where we see a 93 year old jones, and once even saw Ford playing a fifty year old Jones in the series. The grail apparently didn't have the "eternal life" effect on him.
