The world’s oldest people are an endlessly fascinating source of stories, advice and wisdom. To try to gain a better understanding of their longevity, health researcher Jason Prall set out on a global adventure.  His goal was to unravel the secrets of the longest-lived and healthiest populations. The result is a 9-part documentary film series featuring some remarkable characters as well as leading scientists scrutinizing the aging process. The Human Longevity Project visited over 50 locations in 9 countries to study the lifestyles of people that live the longest lives. In this in-depth interview Jason reveals the common traits that appear to promote extended health spans; why he believes simplified living is a key pillar of human longevity and how he applies the lessons of others to live a "longer, happier and more fulfilled life."
