We all know that men and women think differently from one another. This book is written in easy-to-understand language explaining the scientific reasons, both chemically and physiologically, why we are different from childhood to adulthood. It gives examples we can all relate to through different stages of our lives. This is a compliment to books like, "Men Are From Mars, Women Are From Venus" which are written more from the psychology standpoint. After reading this book, I not only understand myself better but why men think differently than women do. Definitely a must-read for both sexes! Very informative and easy to read and enjoy! A female co-worker recommended this book to me after a male friend sent it to her to read. Her father-in-law, who is a retired surgeon, recently visited and began reading it. He was amazed at how well-written it was and, although it was a lot of review for him in terms of the medical side, he was so impressed he asked to take the book with him so he could finish it! I highly recommend it!
