The Cornell Careers Center found that "The most common reason for retiring but continuing to work after retirement is that respondents want a work schedule that allows them the flexibility to do other things, such as travel, or develop other interests (71% gave this reason)." (p.16)

"The Cornell Retirement and Well-Being Study investigates the transition to-and life in-retirement. The focus is on pathways in and out of paid work and unpaid community service, as well as their implications for well-being. Most studies of retirement have viewed it as a one-way, onetime exit, and have examined men’s experiences exclusively. By contrast, we look at men and women, interviewing a large (n=664) sample of 50-72 year olds every two years over a five-year period, from 1994-95 to 1998-99. The study consists of three waves of interviews of older workers and retirees, collected approximately two years apart: 1994-95, 1996-97, and 1998-99. We selected people to study from random lists of workers and retirees (age 50-72 in1994-95) from six major upstate New York corporations. Participating organizations include one university, two hospitals, two Fortune 500 firms, and a utility company. Our original sample, interviewed in 1994-95, consisted of 762 retirees and not-yet-retired older workers.”
