Here's the story of a dedicated fan, told by Matt Damon:

Homeboy Matt Damon, who narrates the 2007 World Series DVD that had its premiere last night at the Wang Center, is proud of his bona fides as a Red Sox fan, one who showed up on David Letterman's show last summer wearing a Sox jersey to diss the Yankees his entire interview. But even the Oscar-winning screenwriter and accomplished actor was impressed by the story related to him by his old roommate at Harvard, Sean Kelly, one of the emergency room doctors from Beth Israel on duty at Fenway Park during the season.

"Anyway, the guy didn't feel well, and after some of the medics and nurses looked at him, it went up the chain to Sean. They realize the guy has had a heart attack, and Sean says, 'We've got to get you out of here.' "

The man had come to the park with a small oxygen tank but still refused to leave.

"The guy says, 'Big Papi is up, and I'm not leaving,' " Damon said. "He said, 'I drove all the way to see Big Papi, and I'm not leaving during his at-bat.' Well, the guy passes out. Sean's got the guy under the bleachers, with the paddles, doing the whole thing - 'Clear!' They save the guy, and he's still healthy. But is that guy a Red Sox fan or what?"

When I'm 85, I can think of worse ways to go out than watching a baseball game.
