Some years ago, there was a very small movement toward designing communal living developments for aging people. Private space combined with communal space, kinda like communes of years past. The idea was for people to interact as wanted and to keep an eye on each other, while still maintaining autonomy and privacy. I thought this was a fabulous idea., particularly as I am in that huge cohort of aging boomers. Sadly, the concept hasn't gained much traction. Over 50 communities seem to dominate the living landscape, which is okay, I guess. I can't really speak to them because I don't know much about them. We have looked at a few. They seem pricey and somewhat homogenous, imo. But, again, I haven't made a study of them. I am sure there are communities to suit all tastes. Just have to find them.
