I up and moved to Europe one year. It took quite a while to adjust, get my bearings, and feel that I was living my own life. While living in Germany, I took a trip to Spain. I loved the sun and the warmer climate, the beauty, the softness of the air. I could tell that it would be extremely different living there. There was an English-language magazine for English-speaking residents, at a newsstand in Granada. I glanced through it, and saw that there was a pocket of social infrastructure for ex-pats. However, the political milieu, the difference in values, in history, in government, in attitudes towards almost everything, would be a major change. It is not a country I would want to be old and alone in. Being old is hard enough, being alone is hard enough, being a foreigner on top of that, in such a different world, would be too much.
It's part of why many of us who had lived in Germany for years and years, returned to our home countries. (I was there fourteen years.)
If I were in my twenties, picking up and going to another country for an indefinite period of time, would be very much in my considerations.
I did it in my thirties, it was much harder.
Being in my fifties, the thought of having to start all over again, to adapt to a foreign culture again, etc., is way too much to consider. The only way I would consider it, is if I had considerable financial resources and could live very comfortably, without any financial worry. And, if that venture into foreign lands didn't work out, that I could return to my native soil without anxiety.
Would you consider moving to a warm climate in a place where you would not need to learn a foreign language?
What about the British Virgin Islands? The advantages to having the protection of one's own government, and citizenship, are huge! Don't know if this is the right link, but, it's a start:

I don't know of another British resort-climate location. Maybe someone else here does.
Please do PM me, if you'd like. This is a huge decision.
