The New York Times article, Grow Old like ‘The Golden Girls’ talks about how people are banding together to live near each other to support themselves as they age. From the article:
They are on to something. “The Golden Girls” living arrangement [Washington Post] is increasingly popular. In these settings, people usually purchase a home together and share expenses, chores and other activities. Housemates serve to combat loneliness and reduce the cost of living. Unlike more traditional retirement communities, these houses are set in neighborhoods that include people of all ages and are often more affordable than traditional retirement communities.

This is another reminder that cohousing – whether senior or not – is a mainstream concept, solving problems for real people.
