According to the National Bureau of Economic Research, people aged 55 or older can work longer, without jeopardizing their health, if they need to.

Nearly 71% of people between the ages of 55 to 59 years old today are in the labor force; however, if the same amount of people that worked in 1977 worked now, 86% would be employed right now. For people between 60 and 64 years-old, the employment rate would increase from 56.2% to 83.2%, while 65-to-69 years-old would rise from 32.3% to 74.1%.
