Hop, skip and jump into this wonderfully curious grand tour of the world of sports, brought to you by QI Elves James Harkin and Anna Ptaszynski. From sport's weirdest rules to its most unlikely heroes, via comically large cricket bats, pole-vaulting priests, creative football chants and exploding billiard balls, each chapter of Everything to Play For is brimming with surprising facts and intriguing stories. Even if you've never asked yourself what David Attenborough has to do with yellow tennis balls, why Victorian doctors feared the outbreak of 'bicycle face' or what led ancient Egyptian athletes to have their spleens removed, this book will give you the astonishing answers - and plenty more besides.
