Did a doctor tell you this, or was it part of a sales pitch from a retirement home representative?
I'm over 60, no kids, have some health problems, and live alone. Unless I suddenly drop dead, I'll probably have to consider the same thing. Unfortunately, since I have no money and haven't even considered getting a burial plot, I'll wind up in the furnace.
I had a friend who worked as some sort of caregiver in different retirement homes, so I may eventually have to consider looking her up and hiring her.
