Something that is popping up more and more are retirement homes or villages. The baby boomers are steadily moving into that stage. With a highly mobile population many choose to live in a retirement home or village rather than be dependant on family who often live great distances away. This doesn't mean they don't have money. In fact many have lots of maney since these homes are quite expensive.
While some of these are simply no children facilities others provide various levels of care from modest housekeeping to food service or medical care (usually an on-call nurse) Of course the more services one makes use of the more it costs.
