I don't like medicine. There's an old Irish proverb that goes, "If I knew where I was going to die, I wouldn't go there." I suspect that I'm going to die in a hospital, so every time I go past one, I drive really quickly to get away from those things. So I spend a lot of money on health: gyms, I go to naturopaths, acupuncturists; anybody else who's almost the alternative to medicine. I think by the time you need medicine, it's too late. That's my belief.
