"Every page of Hammond's books overflows with wit, sensitivity, and warmth." - The Guardian Why does life accelerate as we get older? Why does the clock in our minds sometimes move at a different speed than the one on the wall? Time governs our lives, but how well do we truly understand it? And is it possible to retrain our brains and improve our relationship with it? Drawing on the latest research in psychology, neuroscience, and biology, and on innovative studies on how memory shapes our understanding of time, acclaimed BBC writer and broadcaster Claudia Hammond delves into the mysteries of time perception. Throughout the pages of this book, she introduces us to an extraordinary group of people who have undergone astonishing experiences in the service of scientific research, including the French speleologist Michel Siffre who spent two full months in a completely dark ice cave. This book offers insights into how to manage our time more efficiently, speed up or slow down time at will, plan for the future with greater accuracy, and ultimately exploit the flexibility of time to our advantage. "Hammond weaves a beautifully constructed story of the mysteries that occupy us regarding how we perceive time, and of the modern science that tries to explain them; you'll find that time flies as you are engrossed in the pages of this book." - Mail on Sunday
