A friend of mine recently had a serious heart attack. He was not conscious, and he was in the
ICU for four days before he died. He was on an ICU ventilator, and never responded at all in those four days.
The family felt fortunate that he was kept alive so they could spend time with him and say good-bye, even though he didn't respond.
Sometimes, I think that all the new medical procedures to prolong life are going too far, but when I see a situation like this, I think it's good.
