I tried to track down what exactly kills you, and in essence, "heart failure - your heart stopped working; f*** knows what caused it, could have been a lot of things". I was in the gym at lunchtime and I'd be lying if I said the picture of O'Donnell on the deck didn't enter my head. Has anyone been there when someone's heart stopped working? Was CPR attempted, did it work? I was there when the artist John Bellany had his nationally publicised heart attack, but he didn't look like O'Donnell.
