What do these people have in common?â€˘ The traveling businessman who brings prostitutes back to his hotel room â€˘ The wealthy woman who is arrested for shopliftingâ€˘ The seemingly happily married man who cruises gay clubsThey are allâ€”despite differences in degree, gender, and ageâ€”living a double life, one of our most deeply ingrained, but poorly understood psychological drives. Now, Dr. Gail Saltz steps into the breach to explore â€”in detail and based on the latest researchâ€”our impulse to create and nurture alter egos.Saltz reveals how assuming a different identity can be healthy and tremendously liberating. For proof, we need look no further than the innumerable people who reinvent themselves by moving to the big city, or the countless pseudonymous bloggers. But, as she also makes clear, leading a secret life comes with potentially serious psychological risks. She shows that, in more extreme cases, leading a secret life can have devastating emotional, social and familial consequencesâ€”both for the person leading the secret life, and for those close to him or her.The definitive popular work on how a secret life is formed, lived, justified, and exposed, Saltzâ€™s Anatomy includes contemporary case studies and historical examples (Lindbergh, T. E. Lawrence, Tchaikovsky, et cetera) of people who have risked it all for a taste of forbidden fruit.
