LOS ANGELES - Longtime "Jeopardy!" host Alex Trebek was hospitalized Tuesday after a minor heart attack, a spokesman for the game show said. Trebek, 67, was admitted to Cedars-Sinai Medical Center late Monday night and was expected to remain there about two days for tests and observation, said show spokesman Jeff Ritter. "Thankfully it was a minor heart attack," Ritter said. He did not give other details. A post on the official "Jeopardy!" Web site said Trebek was "resting comfortably in a Los Angeles hospital, and he will be back in the studio for the next scheduled tapings in January."...
