Based on interviews with a wide variety of men and women and research on the literature of adult development, Mark Gerzon answers the question, "Is it possible that human beings experience a profound metamorphosis in midlife?" with a resounding "yes."
Listening to Midlife is a worthwhile read. I made a couple of dozen notes of interesting points. However, I do wish I'd been able to borrow it from the library. Published in 1992, it doesn't quite stand the test of time. The chapters on politics and the environment are quite dated, as is the overall 60's tone of the author.
Pg 79 - "A wedding is not a marriage. A wedding is only the beginning of a undertaking that may or may not, someday, develop into a marriage."
Pg 80 - "Each of us must discover these hidden parts of ourselves, the aspects of our characters that have remained undeveloped. It is the part we have withheld from the world and denied to ourselves ... the 'lost self' repressed because of social pressure ... the 'false self,' the image we present to the world behind which we hide ... 'the disowned self,' qualities condemned in childhood therefore buried."
