The book is presented as 'what doctors really think!', but the author is still on the younger side and does not want to burn bridges, so it's more, 'doctor things that you, the patient, don't know about' - residency, part-time work, the inner workings of academic societies, maintaining relationships despite a heavy, ever-changing workload.
I was probably a bit naive to think that I, a medical interpreter working in large Japanese hospitals for the better part of a decade, would find new info here. A non-medically adjacent person will have more to gain from these pages than I.
