Taiwan is No Country for Old Men.
Apart from my personal problems with humidity, 30-33 degrees most of the year, and too many earthquakes, the mentality here is on the whole unfriendly to elderly people: the lack of courtesy, the crazy traffic with total lack of respect for pedestrians, the scam artists ...
That's why I've been looking around at Spain - so far only on the Internet because retirement is still more than a decade away.
Greece would be my favorite country, but it also has earthquakes, and spending 2 weeks on an island might be fun, but would get boring quite fast for any longer - especially after living in 3-million pop. metropolis Taipei.
If Spain doesn't work out, there's always the old Yugoslavia: Montenegro is the in-place now, but a bit too far from the rest of the world. Croatia would be better, closer to Italy, but already popular for the past 10 years or so.
For those of you interested - CNN had a report recently saying Americans were moving in droves to Latin America, especially Ecuador. It's not my thing because I don't believe it could be any better than Taiwan, and crime might be worse, but who knows.
Sweden, BTW, sounds too expensive and too cold for me, and Georgia smells like Russian tanks. But that's just me. Who knows, you might find real happiness there, it's the new frontier.
