This is the curious story of us and sport. It's about our mind-blowingly determined attempts to be the fastest, the strongest, the most skilful. In this endlessly entertaining tale of play and belonging, astonishing violence and jaw-dropping cheating, we learn what led ancient Egyptian athletes to have their spleens removed and discover why Michael Palin was disqualified from a conker tournament. Crossing millennia, continents and cultures, Harkin and Ptaszynski - the brainy researchers for BBC's QI and co-hosts of No Such Thing As A Fish -show us sport as we've never seen it before.
