On a related issue, there are folks in my town who are working to develop a cohousing community for seniors who are still active. People have their own small homes/apartments, but there are communal dining rooms and exercise facilities and whatnot. I think it's a great idea. Me, I'm not the greatest at co-eating or whatever, but I like the imagination and simplification of not having all that 'stuff.'

I'll bet we are going to see more of these kinds of arrangements among all ages due to economic factors.
