4/5. Physical book. While this book was wonderfully written, a great blend of science, research and human stories, I had a difficult time reading it. As someone who probably has PTSD, it was interesting to read about others who struggle and the various types of therapies that helped them. I was opened up, however, to remembering some traumatizing events in my own life while reflecting. I would recommend this book, but make sure you are in a good place mentally, as it could possibly have the same effect. Overall, I am glad to be done and hopeful for the future of a more trauma-conscious society.
