Not to be disrespectful, but in some situations it is not possible. There are a number of reasons that is not possible, and what you said just laid alot of guilt on a whole lot of people who already feel guilty.
I do think many older people would rather die than to be in isolation. Where I live attorneys on TV are advertising the isolation fact and letting people know to contact them for help. Maybe if a few family members started threatening to sue, things would change
Not possible, or not convenient?
