Is your brain shrinking, and does it really matter? How much of the brain do we actually need? This book challenges us to think differently about the brain, questioning its complexities and contradictions rather than focusing only on its remarkable capabilities. Can we lead a satisfying life even if parts of it are lost?

The bad news is that our brains begin shrinking by our mid-thirties. However, the good news is that they can adapt in extraordinary ways when things go wrong. Dr. Alexis Willett and Dr. Jennifer Barnett shed light on the human brain's capabilities under both ideal and less ideal conditions.

Through accurate facts, case studies, hypothetical scenarios, and interviews with various experts, the book takes us on a journey from ancient times to the far future, exploring different realms of existence.
