This. It's quite possible for the quality of life to go away even though there's nothing on the horizon that will kill or even one catastrophic problem. It can be like your mother--a series of things that add up to being alive but not having any quality of life. I knew someone that chose suicide by dehydration after a fall. They perfectly well knew they had broken their hip and that the healing time for a broken hip (if it even did heal) was longer than their other medical issues would likely give them. Thus they were sentenced to remain lying in bed for the rest of their life. It was only in hindsight that her caretaker realized what had happened--at the time he didn't notice that she was drinking no more than needed to take her pills.
