This is a great series and a fascinating exploration on the longest-living people on Earth. Being a health enthusiast and a civilian longevity researcher, much of the key concepts in the film are not foreign to me, but what must be said is that this film often expands upon the detail or portrays the concepts in a way that is both accessible and refreshing. You can easily tell from the scripts that Dan Buettner is operating at a very high level when it comes to the different aspects of longevity, and this film definitely doesn't disappoint whether you're new or old to this topic. The quest of longevity through knowing how to live is a worthy pursuit for all humans who are still living, and this film can provide the inspiration and the tool to make that a reality.
