Nicoya, Costa Rica is, according to Dan Buettner, home to the 'most extraordinary centenarians on the planet'. One which, for many years, he contends, went unnoticed because researchers couldn't believe the residents of 'such a poor country' could possibly live past 80, let alone 100.

In this very special episode of Blue Zones: Revisited (recorded live in Costa Rica!) we question exactly how 'poor' the 'Rich Coast' country really is, whether or not it's better to have a plan de vida or a pura vida, and whether pork lard and eggs constitute a 'plant-based diet'.
