When I moved in to my Arlington colonial 26 years ago, my neighbors ranged from young families to older residents, some of whom had been in their homes for over 40 years. Over time, I observed the changes that redefined their later lives, like the widow who had to move into assisted living. Having spent my career in the field of aging, health and long-term care, I was acutely aware of how supportive communities might make the difference in helping my neighbors to live their later years with health, dignity and independence.
