I saw the writing on the wall ten years ago and opted for leaving early (after 32+ years). Also, after five years on the civilian side, the writing was becoming evident again, but this time it was taxes and immigration that was rearing its head.
Took the plunge and opted for a more manana attitude..., lucky that I was working from home, so could operate from anywhere, provided that there was broadband and an airport near at hand. Now nearing my fifth year in the sunny med and still working for the same US company that I joined after retirement from RAF.
So it can be done..., its just a matter of looking at your options, finding a place that you like, a house that you can afford, a pool big enough for the Grandchildren, and a bit of luck...., and its amazing how many 'old pals' suddenly appear out of the woodwork when they hear you have moved to sunny climes!!
