I think you
are the unusual one for deciding to do it
So many of the people we spoke to in England were very much "oh, it's too late for us", "there's no point". C'mon guys, where your sense of adventure eh? Also, I think people get tangled up with the "well, the kids are settled in school" (travel does them good), "My parents are going to need support in a few years time", "what about my pension", "I've got a good job", "what shall we do with the house?" and before you know it, the opportunity's gone.
I think it comes down to imagination, and a lot of people don't have it
