Nicholas Hobbes tackles the sports-related questions that thousands of people have debated in front of the TV and in the pub, but for which they have never found a definitive answer. These include: Why do female tennis players grunt? Are English footballers really thicker than foreign players? Why do cyclists shave their legs? Can one swimming pool be 'faster' than another? Who would win a fight between Muhammad Ali and Bruce Lee? Drawing on studies by statisticians and scientists, doctors and philosophers, Nicholas Hobbes explains the whys, whats and hows, so you don't have to.
