A cornucopia of theories, conundrums and fascinating morsels from the irrepressible Peter FitzSimons.

Why does the dominant partner in any sexual relationship usually sleep on the side of the bed nearest the door? Is there a direct relationship between the length of hemlines and the state of the national economy? Are odd numbers evil? And why do drivers with hats drive 40 kilometres per hour slower than those without?

These are the big questions of life, and it takes a brave man to tackle them. The Italian versus Australian theory of traffic lights; who gets the spare armrest between aeroplane seats; why men fall asleep after love-making . . . In this updated edition of the best-selling Little Theories of Life, author, broadcaster and columnist Peter FitzSimons is your ideal guide to the weird world of the popular theory, the urban myth, and the land of 'did you know . . .?'.
