Very glad you're OK Irving. Lots of people have become paraplegic from that stuff. Don't discount the employment risk for the long haul, you're worth keeping around awhile.
My minor experience with that was scary enough. I've never fallen off one but did fall through one. Reroofing 4000sf w/ 2/3 of it redecked, I slightly spaced that one smaller OSB hadn't actually been nailed in place yet as I was walking backwards up the roof. It was like a cartoon with a trap door where you're there, and suddenly your not. Flat backed into the attic space but only about a 4' drop. That was enough of a wake up call to be much more careful.
