It's a messy business, dying,' he said. 'As time goes on there's just less and less of you. It happens quickly for some; for others it can drag on. Starting from birth you keep losing one thing after another: first a finger, than an arm, first a tooth, then a whole set of teeth, first one memory, then all your memory, and so on and so forth, until one day there's nothing left. Then they chuck what's left of you in a hole and shovel it in and that's your lot.
