My Uncle Mark has always told me that "men are simple creatures." I think most women would agree, if by "simple" you mean incomprehensible, ego-driven, and just plain weird. But are men really so out there, or do women just make them seem more complicated due to our own inability to grasp men's fundamental simplicity? The Why Chromosome: Unraveling the Mystery of the Modern Menigma goes beyond just determining whether or not a guy is into you. This book is a dialogue between the sexes, about the sexes that deconstructs not only the whats but the whys of some of men's most flummoxing behaviors. Learn how to avoid falling prey to the dreaded "McRib Syndrome", find out what it really means when guys just say no to sex, and discover why men just can't seem to resist the ever-seductive lure of the psycho-bitch. The book consists of forty questions spread across five sections: meeting, dating, relationships, breakups, and sex. Each question is followed by a description of the behavior and a theory of why it occurs written from a female perspective, rebutted by the answer straight from the source - a man, well two men actually. In response to each theory a self-described Good Guy and his Bad Boy counterpart give women the low down on some of men's most messed up behaviors.
