What made you the person you are today? Renowned neuroscientist, broadcaster and author Dr. Hannah Critchlow explains how the answers to fundamental questions about fate and free will lie in our understanding of the human brain.

In this investigation Hannah reveals how neuroscience shapes our lives, drawing vividly on everyday life to show the potential, as well as the dangers, of being able to predict our likely futures.

Her latest book, The Science of Fate, which made the Sunday Times Bestseller list, is a highly accessible and awe-inspiring examination of the science of who we are.
