There is a movie where the dad is dying of cancer. First the son brings him heroin to the hospital and later near the end they all come together and he overdoses and dies in peace. That's the way I want to go out. I have seen people who died in hospital with all kinds of machines hooked up, constantly being probed and relatives telling to keep "fighting". It probably depends on your personality but I prefer to go out at my own will in peace (and high on drugs). I don't want to keep fighting.
