We’ve been told all our lives that doing certain things will help us live longer. Eat plenty of vegetables. Avoid sugar. Drink lots of water. Exercise regularly. We can hear our mother’s voice right now. These habits are definitely more helpful than harmful, and longevity expert Dan Buettner agrees — kinda. He examined the regions with the longest-living populations in the world, where residents are 10 times more likely to reach the age of 100. These regions include the Barbagia region of Sardinia, Italy; Ikaria, Greece; Nicoya Peninsula, Costa Rica; Okinawa, Japan; and the Seventh Day Adventist community in Loma Linda, California. Buettner discovered nine common characteristics in these “Blue Zones.” Dubbed the “Power 9,” these “rules” don’t include fad diets, impossibly difficult workouts, or expensive wellness products — just small changes to your everyday routine.
