Older Americans who work spend differently, study shows

There's a popular notion that many older Americans choose to work because they have little other choice. Unable to afford retirement or health care, so the belief goes, those in their 60s, 70s -- and sometimes beyond, stay on the job to pay bills.

A new study by University of Missouri researchers debunks that myth, showing that older workers aren't necessarily working out of necessity. Further, data revealed older Americans who work showed different spending patterns compared to those of non-workers.
