We have some family members who cared a lot about him and have very deep pockets, so they assembled a team of the best specialists they could find over a variety of disciplines and demanded they throw every treatment possible at him to try to keep him alive. So in his late 80's, with terminal cancer, they have him on chemo, pumped full of an ever changing diet of pills, going through one invasive procedure after another. He was a smart guy too and I think he hated it but didn't have the heart to tell his family who thought they were doing the right thing to stop.
All for what? To keep him barely alive hooked up to machines for an extra month or two? It was one of the saddest things I've ever witnessed that that is what the end of his life had to look like.
