There are a lot of places I would like to live that weren't listed here (Iceland, Scandanavia...) but I picked Italy. Because when it came down to it, I could pick China because it's my area of study, but I don't think I could deal with all their... rules. I also considered England, because I've been there before and I really loved it! But their food wasn't too great, for me, anyway.
So I finally picked Italy! I've been there, too, and the have amazing food. And even though there'd be a language barrier, I think the idea of living somewhere so old and yet so vibrant would be amazing.
My second choice would be Brazil. If anything, so that in May-August I could go there, and experience cold weather, instead of suffering through another summer in Florida. xD
