In the US – where they do this kind of thing very well – the University of Washington’s Institute for Health Metrics and Evaluation has come up with a puzzle.
If you live in certain counties of Colorado you can expect to live beyond the age of 85. But if you are unlucky to live in certain parts of South Dakota you are destined to pop your clogs by 67.
And if you live in parts of Kentucky your life expectancy has dropped by more than two years since 1980. Whereas in parts of New York State your life expectancy on average has grown by 15%, giving you an extra 10 years, since 1980.
