The country is aging and so is the workforce. According to the 2012 Census, there were over four million full-time workers age 65 and older. The aging process can bring with it a gradual decrease in vision, hearing, and physical abilities. Jobs that were once easy for a 30 or 40-year-old to perform can become challenging for a 60 or 70-year-old. For example, in our work, some veterans have told us that war wounds sustained in the 1960s and 1970s are only now starting to take their toll, inducing new mobility and dexterity limitations.
