Live where you have friends and family if at all possible.
If you don�t have friends or family, it doesn�t matter.
Personally, having no wife, no kids, few close friend that are older than me, and a few close relatives that are older than me, I expect I will move to somewhere I can practice my hobbies when I retire 20 years from now.
On the other hand, will I really ever truly retire. If I didn�t have something to get me out of bed would I?
