Cold maybe not, but heck I can always build a fire.
I live in Europe and Finland has a reputation that is a bit unusual. We had a bear problem in Germany back around 2006 (something that hasn’t happened in 150-odd years), and they finally ended up calling up a Finn bear hunter group. There were daily status reports of the Finn hunters and it was like a bunch of Ozark Mountain men arriving in NY City.
Finns drink an awful lot. Finns are terrible at social occasions....avoiding face-to-face contact and often talking to someone at an angle...just to avoid the eye-to-eye situation. Finns tend to think about things an awful lot....to the ninth degree.
So I don’t think it’s just a migrant thing. You could take a couple of Americans and send them there for a year, and even they would start talking about the problems of adjustment.
