re: What’s the youngest age that a friend of yours retired?

I have a cousin who retired from the marines when he was 39 or 40, he was an e-9 and has full disability. He did go back to school and get an MBA, but hasn't gone back to work yet. His wife has a good job.

My grandpa retired when he was 50 years old as chief of detectives of Baton Rouge PD back in the early 80's. He lived until he was 87,retired out in rural Vermilion parish where he had some family land, he hung out with friends every day, played cards, fished, cooked competitively at cookoffs, etc... Lived a pretty damn good retirement.
