This book was good, but boy was it long. It definitely feels like a better book to read than listen to because there was so much science that sometimes it was hard to keep up. Otherwise, I think this book was informative and interesting, but it was sort of bland. Kind of just stating facts and studies, many of which were really interesting, and I think the way the info was organized was good, but it didn't leave much of an impact. I think the book lacked some conviction, which made it somewhat boring to read despite the fascinating nature of the science presented. Either way, it was informative and compelling, it just needed a little more oomph for me.
