Its funny, people do only focus on the 'ooh long winters' (my parents do this) without considering the other side of the scale that makes their life miserable in the S of England - congestion, aggressive people, litter, expensive everything, fumes, aircraft noise, lack of space, lack of privacy, overcrowded public transport. For me the wind and the long winters are offset. Also, long winters are quite nice when you are snuggled up with a roaring fire, peace and quiet and homemade food off your own land.
I agree there may be advantages then in looking further afield abroad as well as to the far north tho I think the reason that a lot of people dont is that there is the language barrier for many people, they arent familiar with the culture and the costs of moving overseas with shipping etc is a lot more so it feels like a bigger step.
