I've always said that I'm only here till my next work permit expires. Not too sure if I could live here on a tourist visa (although these days I could go for the marriage visa option, but I'm not overly happy with the reliance of the "wife" thing for one of those )

EDIT - I should add that for me the consideration has never been whether or not I could live here forever, but whereas I could live. I cannot see my wife agreeing to go and live back in Africa and Europe is not the sort of place I want to live. The hunt goes on.
