This book should be a compulsory reading for all health-care professionals, particularly medical doctors. The "philosophy" of the book is about joining forces and perspectives between different occupational groups around health-care.
Medicine should, at first, aim at maximizing the health benefits that can be accomplished by lifestyle choices: exercise, nutrition, mental well-being etc. This calls for the aforementioned collaboration between experts of different areas and free thinking with open-mindedness for rational critique. And only after that, the possible remaining need for help should be "completed" by pharmacological agents.
Today, sadly, it's the other way around.
I hope that some day, the term "Medicine" would include other, just as scientific forms of help - not just pharmacological or surgical.
