A Short History of Falling - like The Diving Bell and the Butterfly, and When Breath Becomes Air - is a searingly beautiful, profound and unforgettable memoir that finds light and even humour in the darkest of places. As I get weaker, less a part of this world, or less a part of what I love, less a part of my family's life, I can perceive its edges with fantastic clarity. I can lie against it, lolling my arm over the edge, running my fingers around the rim. And this is where I am. In 2018, Joe Hammond, wrote a piece for the Guardian about the 33 birthday cards he was writing for his two sons.
