The Longevity Project by C.S. Friedman

Drawing on an eight-decade longitudinal study, this book examines how lifelong patterns—especially personality traits like conscientiousness, stable social connections, sensible work habits, and effective coping—affect how long people live. It challenges simplistic health myths, showing that childhood characteristics and consistent behaviors over time often matter more than short-term interventions, and it offers evidence-based insights about how relationships, purpose, and everyday habits contribute to healthier, longer lives.
