My father got one about 2 years ago, has had a heart attack & stroke at 72, would have died peacefully after 20 years of CHF, but his defibulator kept bringing him back, he can barely speak, can't set up or reposition himself, can't feed himself, has said many times since he's tired, he wants it done, they can't turn it off because he doesn't have a living will & every time it goes off it kills a little more of his heart, so it is dragging it out until it kills all of
