No sugar, no alcohol and lots of downshifting: The nine healthy habits I picked up at a blue zones-inspired retreat.

I first heard of "blue zones" when my already documentary-heavy Netflix algorithm recommended Live to 100: Secrets of the Blue Zones as a follow-up to bingeing various Planet Earth seasons (rare crossover viewing for me, my 4-year-old and my 10-year-old). I was immediately intrigued by these zones around the world that have the highest proportions of centenarians — and where folks live an average of 10 years longer than Americans.
