Probably more of a 3.5. A bit longer and drier than your normal pop-science non-fiction, but a really important and interesting topic that I'm really glad to have learned a lot more about. A predictably tough listen, and I couldn't help but wonder what the main benefit is of including quite so many anecdotes of individuals' experiences across so much of the book, when we should base our decisions of medical treatment on studies and their meta-analyses. Perhaps simply highlighting examples of the human experience of the symptoms and lived experiences of PTSD and what successful treatment looks like helps to illustrate and drill in that intrinsic mind-and-body connection. Perhaps it'd just be a much drier and more boring book!

My main takeaway is a deep appreciation for the way my mind is my body -- my muscles, my posture, my heart rate, my nerves, my neurons -- all are intrinsically tied together. Mental health and physical health are not exclusive facets of ourselves. It is all one's general health, and our healthcare systems should treat it as such.
