The problem is, as habits they don’t last. It’s said that diets fail for 98 percent of the people who start them; gym memberships last on average nine months; and people only take pills for about three years before they get bored with the habit. After studying Blue Zones for nearly a decade, the big aha for me is how the agents of longevity reinforce one another for the long term. If you want people to adopt a healthy lifestyle, you need to build an ecosystem around them. As soon as you take culture, belonging, purpose, or religion out of the picture, the foundation collapses.
