If you are interested in longevity and how centenarians live (like I am), then I highly suggest reading The Blue Zones: 9 Lessons for Living Longer.
Bestselling author, longevity expert, and National Geographic Explorer Dan Buettner reports on health, fitness, diet, and aging, drawing on his research from extraordinarily long-lived communities–Blue Zones–around the globe. Buettner has launched a major public health initiative to transform cities based on principles from this book, an updated and expanded edition of his bestselling classic on longevity. His prescriptions for lifestyle, nutrition, outlook, and stress-coping practices will add years to your life and life to your years.
