Seems strange to me to have little if any knowledge of the culture of that country yet want to live there. You should definitely at least go for a month-long visit or so before making that decision. Here are a couple of things that come to mind: on average men die in their late fifties (it's been dropping again), no freedom of speech, by midcentury the Russians will be a minority in their country because of birthrates. Of course, America is heading in that direction as well.

I too would be interested in knowing what you have based your decision on.
