I remember a newspaper article about a gent who had passed away at around 100. He had retired from running his own business, but needed a purpose and got a job as a Walmart greeter. He didn't need the money, but he thrived at this job, and did it for decades until he could no longer get up in the morning, and then passed away.

Having a job where you get up, go out, do something useful, and interact with others is good for the soul. Sitting at home by yourself watching TV is a recipe for decline and death.
