This may be an academic topic for most as looking at national life expectancy numbers doesn't tell you very much about your own situation as far as factors like health history, the risks you take, and health history of your relatives, etc.
However in some cases it's worth looking at particularly for older Americans deciding when to start their social security benefit.
Being American, I looked this up and was kind of surprised to learn that the Thailand life expectancy is much higher than in the US.
I wasn't surprised at all to learn that U.S. life expectancies are much lower than other "advanced" western countries though.
U.S.
Men 73.1 (BAD!)
Women 79.1

THAILAND
Men 75.75
Women 84.08
So long term expats, are we in the Thai bucket or stuck with our home country?
