People preparing for retirement have a lot of things to consider—how much they've managed to save, whether they'll have adequate health care, where they might want to live—and putting all the pieces together can be tricky.

The wrong choice in any of these, and more, can mean a miserable retirement, in which money is tight, health deteriorates and seniors feel isolated and alone.

But thanks to a Gallup and Healthways'2015 State Well-Being Rankings for Older Americans (in case you're wondering, despite the fact that the report has 2015 in its title, it includes data from the first quarter of 2016 and is the most recent one issued on the topic), people considering relocating (or, for that matter, staying put) for retirement have some guidance on places where they might not do as well as they'd like.
