The median lifespan in the United States today is nearly 79 years. Like all medians and averages, your mileage may vary. In some U.S. towns and cities, the median falls to around 68, and in others, it rises to more than 85.

Dan Buettner, founder of a movement called Blue Zones that helps communities set policies to help residents live longer, comments, “If you want to live a long time, the best thing you can do is move to a place where people are verifiably living the longest.”
