“Workers 50-65 who plan to retire by age 65 (65%) were more likely than other respondents to identify the need for health benefits. In fact, the need for health benefits was the issue that workers 50-65 who plan to retire by age 65 named more frequently than any other issue as a major reason for considering work in retirement", according to a 2005 AARP report.

"This survey of individuals ages 50 and older was designed to gauge reactions to the concept of phased retirement as outlined and to determine the extent to which phased retirement would encourage workers near traditional retirement age to remain in the workforce longer than they would have otherwise...Conducted from January 6th through January 15th 2005, the survey was fielded to panel members who were ages 50 or older...A total of 2,167 individuals participated in the survey. Of all respondents, approximately one-third were workers between the ages of 50 and 65 who plan to retire by age 65, about one-quarter were workers between the ages of 50 and 65 who plan to continue working beyond age 65, approximately one in ten were workers ages 66 or older, and the remaining one-quarter were individuals ages 50 or older who are currently retired."
