I may have missed it, but I was fully expecting to see something about the Military here. At least for USA based persons. I have several friends that are beginning to retire or thinking about retirement in their mid to late 30's.
Full health insurance, and a pension for the rest of their lives. It may not be a ton in all cases, but most of my friends are young enough to pursue whatever they want with a ton of financial security if they so desire. Or go chill in a van down by the river.... either way it's a decent option.
