The funny thing is, most of the people in these communities don't exercise in the way that we think of exercise Buettner says. They eat a plant-based diet and have a support network of people they can lean on throughout life, but they don't go to the gym. They don't hop on a treadmill. Instead, they perform regular, low 10. physical activity because of the way their lives are structured.
