We live in an age where stress is treated as the ultimate enemy-something to escape, suppress, or eliminate. Yet despite meditation apps, productivity hacks, and endless wellness advice, burnout is at an all-time high. What if we've misunderstood stress entirely? In Good Stress, Bad Stress, India's leading longevity physician and performance specialist Dr. Marcus Ranney flips the narrative. Drawing from two decades of work and research with elite athletes, explorers, astronauts, military units, corporate leaders, and everyday high achievers, this book reveals a powerful truth: stress, when used correctly, is not destructive-it's transformative. Structured into ninety-nine short, actionable chapters, Good Stress, Bad Stress gives you tools you can use immediately-at work, at home, and in everyday life.
