I live in an active adult community, but it's not age restricted so there are some people below 55. Since it's small (76 condos), there are no major activities, just a clubhouse and a pool. It suits us for now. But when the time comes that we can't drive, that's where the problem lies.
Some of my older neighbors say they consider their lifestyle to be assisted living. They have someone come in and clean and they go out to eat a lot.
As far as I can tell, the 55+ communities have lots of activities but no real support for persons who need help with driving/cleaning/cooking. So for true aging issues, it seems that you would have to live in a community with different levels of care (where you start off with independent living and then can go to assisted living if you need it or a (please, please, please---anything but!) nursing home if needed).
SteveR, I thought most 55+ communities allow grandkids to live for up to 3 months, like for summer vacation?
Caroline and happy2bR, as a recovering introvert who (thanks to retirement wants to connect more with people), do you really think you could handle all the social interaction? Would the types of clubs and activities they have interest you? Unfortunately, for us introverts, much of what we like to do is solitary type activities!
