A part-time job in retirement can be good for health, bank account

The idea of working in retirement may seem unappealing to some older adults, but it has become a popular facet of senior living. Part-time jobs offer those who have left the workforce a number of benefits ranging from improved health to greater financial security, according to U.S. News and World Report.

The supplemental retirement income a part-time job offers is the most obvious advantage, even for seniors who may be able to live comfortably once they've left their previous job. While they may not need the extra cash, getting a paycheck provides the opportunity to live a more active retirement, whether it is through traveling or heading back to the classroom.

Working in retirement also provides some social benefits that can play a role in healthy aging. Many people enjoy the camaraderie and daily interaction offered by a job, and part-time work certainly provides them with that, according to the publication. In fact, a 2009 study out of the Rush University Medical Center found that seniors with a stronger social network enjoy better health.

In a similar vein, working a part-time job in retirement may be good for mental health. Keeping the mind active is one of the best ways to stay sharp later in life, and regular mental engagement certainly goes a long way in helping seniors do just that.

The benefits of working in retirement have not gone unnoticed by many older adults, according to a recent survey from Civic Ventures. Approximately 9 million people between 44 and 70 have entered an encore career, and another 31 million people in the age group have expressed interest in doing so.
