The increased interest in employment of older adults is motivated by several factors. First, the American work force is aging. The baby boom generation is getting older and is succeeded by a declining number of young people entering the work force [1]. Second, increased life expectancy rates combined with a continuing trend for early retirement amplify the economic burden of retirement on society [2]. Third, the economic reality for many older adults includes lack of sufficient income and benefits which require their continued involvement in the work force [3]. And, finally, many older adults can anticipate a prolonged and healthy aging and are interested in continuing their productive involvement in society [4]. // (1995)
