There is no indication he won't play at a high level for the next several years. Even when injured, he still plays at a high level. See a few years ago when he played with one shoulder and last year with the bad wheel. Dude is a freak, and now that he cut sugar out of his diet, he will more than likely lengthen his career. He will be a first ballot HOF'er when all is said and done, IMHO.
