I had a couple neighbors who retired at around age 50 from a GM plant. Neither made it to age 60.
My parents have lots of friends who have retired, and after 6-8 months, they are bored and trying to go back to work. Even my MIL who is 76 still works 3 days a week. She says it keeps her young and mentally sharp!
The ones who stay “retired” all seem to die within a few years. It’s like they have no purpose in life and just fade away.
