Query: Should be renamed the molecules of Emotional Egos

The title is fascinating and every now and then the author provides some interesting insights into how neuropeptides and emotions are related. Unfortuately, she spends most of the book talking about her life and little about the science or even the theories of emotion. Her science appears very narrow and limited to her work and she misses in educating the reader about the role of simpler things such as steroids and the immune system.She does not address her own basic motivations for life, which appears to be to get recognition for her work (the recognition is much more important than the quality or nature of the work). I would hope that her next book focuses on the science of emotions since she failed to discuss some of the more interesting emotions related to the key events in her life (marriage, divorce, childbirth, rejection) and how these emotions are needed for human survival.
