There's really no such thing as the agony of dying. I'm quite sure that pain is shut off at the moment of death. You see something happens when the body knows it's about to go. Peptide hormones are released by cells in the hypothalamus and pituitary gland. Endorphins. They attach themselves to the cells responsible for feeling pain.
I don't have a fear factor. Well not much of one. And I'm willing to risk quite a lot - as a comedian you're always risking a lot. You're risking failure especially if you're improvising and going on TV shows trying to make comedy out of thin air. That is quite a risky business.
