What is the first question our parents asked about us after we were born? Probably, 'Is it a boy or a girl?' No single fact about us is more significant than our sex. In any human culture, it determines how others react to us and how they treat us. "Viva Le Difference", a light-hearted exploration of sex differences, shows how this view violates not only everyday experience and common sense, but the accumulating evidence of science that men and women are profoundly different creatures. Authors Anthony Walsh and Grace J. Walsh begin with a look at the genetic and hormonal bases of sex by viewing maleness and femaleness as a continuum based on the degree of masculisation of the brain. Next, they explore different sexual aspects of the human body other than the reproductive organs. They look at size, strength, and endurance, and many other differences in capacity, as well as sensory (eyes, nose, ears, etc.) differences. From there, the discussion focuses on differences in the brain and mind, health and illness among men and women, and the different ways in which men and women experience emotion, with an emphasis on that most intense emotion of all - love. Informative and entertaining, this book offers a fresh, insightful, and lively look at what makes men and women unique.
