"Was mich nicht umbringt, macht mich stärker." Okay, Nietzsche may not have had my reading this book in mind when he said that, but, true, this was a bit of a struggle for me to read, and I feel stronger for having done so, in the end. From facts offered by the author that I may never fully grasp, to facts abundantly clear to me even before reading this book, but now confirmed by one really sharp guy, and everything in between, this was quite a roller coaster ride for me. Folks, this is the full meal deal on behavior. From brain cells to prison cells, how and why we do what we do is in here. In my view, a reader simply has to read it to find out fully what I mean. I will add just this: I hoped I would find some insight into how very differently large segments of the American public is behaving, of late. I had my suspicions and my beliefs about that going into this book, and I was not disappointed. Much of what I already thought might be the case, has been confirmed or clarified, but, most importantly, I now am much better equipped to absorb and respond in meaningful, precise way to what I am apparently destined to confront for the next several years at least. I admit, one shouldn't have to read this book before confronting your errant relatives at Thanksgiving dinner, but -- trust me -- it would actually help.
