The AARP just published a study that they did about the healthiest cities for seniors. They used 20 measures of vitality. They looked at the physical aspects of the communities, as well as the health and habits of their residents and determined that Ann Arbor is the best U.S. city for seniors! There are also so many things to do in this town to keep people happy. I think it's a great city for people of all ages, and I appreciate the nod of recognition from AARP. Here's the link to the article if you'd like to read more.
