In “What’s the Smartest Age?”, author Kunal Kapoor takes readers on a powerful journey through the human mind at every age. Blending warm storytelling with research from psychology and neuroscience, the book uncovers how intelligence evolves from teenage curiosity to adult strategy to the rich, layered wisdom of later life.
Discover why fluid intelligence peaks early — and why that’s only part of the story.
Learn how crystallized intelligence grows with time and experience.
Understand the power of emotional intelligence, and why it often peaks later in life.
Explore why there’s no single “smartest age” — because each stage of life carries its own kind of brilliance.
Insightful, calming, and deeply human, this book isn’t about chasing lost sharpness — it’s about recognizing and celebrating the intelligence that’s already within you, right now.
