Dr. Lee Berk: That is, that's amazing. If you or I had come up with a medication that did something like that, we'd be on our way to Stockholm Sweden.

Jennifer Matthews: Felten says every cardiac rehab program should include laughter, the kind that comes from the belly. Paul Baehr: I watch, you know, America's Funniest Home Videos. I like that.
