Most doctors don't accept this sort of end of life care. We should stop making it the default and make it elective instead. We treat animals far more humanely, allowing them to be put down when their quality of life goes down without much hope of improvement. Right now, if I want to avoid the nightmare fate of elderly or permanently ill people, I would have to commit suicide ahead of time. I would rather have a humane system that could take care of that when I am too far gone .
