The book helped me try to stress out less about some frightening RSI I had years ago. The speculative mechanical explanation for the "stress -> pain", something like: stress means less oxygenated blood to extremities, was never convincing - more like a dumbo's feather for those skeptical of general mind-body woo.

Coincidentally, I got better. That was probably just rest and time, but I'm grateful that the book helped me not worry so much.
