Fretting about her family's health and eating habits, Marta Zaraska fasted, bought goji berries and chia seeds, and ran a half-marathon. Studying available research in many disciplines led Zaraska to a simple conclusion: In addition to healthy nutrition and physical activity, we can improve our lifespan by deepening friendships, practicing empathy, and volunteering our free time. Sharing her own journey toward living a fully realized life, Zaraska recounts catching wild mice in an English woods, flower arranging with Japanese octogenarians, and visiting "hugging centers."
