As a fellow survivor of heart surgery, Letterman said, “It just didn’t make any sense to me. After what these guys did for me—they opened me up, they took my heart out, they put me on a heart-lung machine for forty-two minutes. And then they put your heart back in and they stitch you back up. After people have gone to that trouble, the last thing in the world you’re going to do is ruin it by killing yourself.”
