I spoke with a critical care specialist two days ago who sees only more suffering for the elderly in the future. The US population is aging and a small minority have determined their end-of-life desires. Many of those who have not thought ahead, will suffer a prolonged death.
Most people would not want extraordinary medical measures that would only prolong their death. They would prefer a natural death at home, yet very few people have taken the needed steps to insure this occurs. If you or your family member have not dealt with these matters, discuss the issues as soon as possible with your physician.
