Yeah, I've done it, and might be doing it again later this year.
Did just short of 8 years in the RAF as an Air Communications technician, but got invalided out after a nasty motorcycle accident. Fought with all kinds of physical and psychological limitations for 6 years after that before finally getting a job in the parts/accessories/clothing dept. of a local bike dealer, then did about 7 or 8 years just moving from dealer to dealer, more for a change of scenery and pay increases that came with each move than anything else.
Then out of work for a couple of years again, until getting a job in the returns dept. at Oxford Products. Did that for a while, with about a year's break to go off backpacking for a year or so, and now out of work again while I sort a house (done), another bike (done), and a nice big Euro tour on the bike (not done...yet). Then it will be back to finding something else to do for a living again. Got a couple of ideas, nothing spectacular, but if I can land a job working with people I get along with, that'll do.
