This is a risk I think that people don't give enough consideration.

I know a guy who FIREd a while ago, long before we called it FIRE, and he's had a heck of a time landing another corporate job. He had a very successful business development firm and took a buyout from partners so he could move away from NYC and spend time with his kids. His kids are all grown up now and he's been looking for jobs and...crickets.
