Black beans and soy beans are the cornerstones of longevity diets around the world.

Diet and supplements and exercise programs aren't what is achieving longevity. Having a faith-based community can add four to 14 years.

The secret to longevity, as I see it, has less to do with diet, or even exercise, and more to do with the environment in which a person lives: social and physical. What do I mean by this? They live rewardingly inconvenient lives.

Select your friendships carefully. Gather people around you who will reinforce your lifestyle.

When you look at any great team, one thing that they have is longevity on their staffs. When you are together for a number of years, things become habit. When you develop good habits, that filters down to the community and players.

Exercise, from a public health perspective, is an unmitigated failure. The world's longest-lived people live in environments that nudge them into more movement. They don't use power tools, they do their own yard work, they grow a garden.
