We live in a culture where after age 18, you're considered weird if you live with your parents and after your earning years end you're considered a burden. It's the old pick yourself up by your bootstrap philosophy. There are lots of cultures that consider the extended family to be central to survival. Having said that, I have decided not to treat any life threatening physical problems after age 78. That's the average lifespan in America. To try to extend that time is expensive and often reduces the quality of life. I also am exploring ways to end my own life if I have signs of cognitive decline. We doubled the average lifespan not long before I was born, 1951, but didn't necessarily improve the longterm quality of life. Too many people are living far too long. That doesn't appeal to me in the least.
