Bob Marley ultimately died from a friendly soccer game with a couple of Germans. He got an infection in his toe and being a Rastafarian did not believe in amputation. Due to the religion he created, I don't think he did much suffering though... rather he died happy.

Not going to touch the Steve Irwin subject, but will say that he made me smile.

Wasn't there a U.S. Senator or Congressman who died from a heart attack right after he orgasmed with/in his mistress. What a way to go!
