Staying healthy isn’t just about diet and exercise. It also comes from strong and lasting friendships. Studies show that time spent with friends helps us to stay healthy and potentially live longer. And while you can "connect" on Facebook and Instagram, the real benefits come from live, regular, face-to-face interactions, even if they're via Facetime or Skype. Consider scheduling routine get-togethers with friends to share successes, failures, and the unique life-wisdom that each of you has to offer—and see how good you feel!
