Or it might not since chance goes the other way. My point is not to encourage people to live in an unhealthy way but to challenge the flippant suggestion that anyone who has serious health problems with age deserves it for their unhealthy lifestyle.
It is personal for me. My grandfather spent several years spoon feeding his mother who had severe dementia. He didn't resent her. He loved her but it still impacted him. When his own health later degraded to the point where he was going to need more care from the people he loved, he couldn't live with the thought of losing control and being a burden to his children so he ended his life. It was not a spur of the moment decision. He had all the legal and fiscal matters lined up. He even had his tombstone in place. He lived a full life with lots of close family and friends. Was he a coward or a saint? Maybe some of both. Maybe neither. Maybe he was just practical to the end. I haven't figured it out.
