Turns out there's more to the best retirement spot than sun and sand. When ranked on a healthy, active lifestyle and access to quality health care, the Provo-Orem area ranked tops for large metro areas, according to one 2012 study. Other reasons for its top marks included a sense of community, high rates of volunteer work, and plenty of continuing-care facilities. Sioux Falls, SD, was No. 1 for small metro areas.
Bottom line: What makes somewhere the best is up to you. Taking into account how close you are (or not) to family, ability to safely drive and easily walk places, and the support services available may be other things you want to consider.
