The longtime host of the popular game show has had a pretty hairy health history lately. In June 2011, Trebek, 72, was robbed in a San Francisco hotel and tore an Achilles tendon while chasing the thief, so that might have kept him less mobile for a while. And in June, Trebek had a mild heart attack — he had had one before, in 2007. But Trebek has been back in action since late July filming the 29th season of Jeopardy!, which begins airing Sept. 17.
