What Buettner and his team have done is studied how people live in these blue zones to try and discover why they live up to a decade or more longer than the rest of us. What it boils down to, if their theories are correct, at least, is fairly simple. The people in those communities eat less and eat mostly plant-based foods. They have less stress, they indulge in a glass or two of red wine, and they incorporate physical activity into every day. Essentially, less is more.

It's difficult to make changes like this sometimes in our Western culture, but it's clear that these communities are doing something right, as far as longevity goes anyway. To learn more about what makes the blue zones special, check out Forbes gallery on the subject.
