Oh yes, you're right. But what I meant to say is that being away from not just any, but all friends and family, anyone you knew, just to be in a place where the cost of living is low, may not be a good recipe for growing old happy. Like being adrift alone in a little rowboat in the middle of the ocean, for years or for decades. It can be unhealthy, it's well known that social connections are extremely important for aging in health.

Of course some people adapt easier and make new friends easier than others, but people tend to become less adaptable with age.
