Introduction

In an idealized world of medical practice, you would go to the doctor, describe a few symptoms, undergo a few tests and then listen carefully to the doctor’s diagnosis, prognosis and prescription. The diagnosis might well be due to something entirely out of your control and the prescription would often be a pharmaceutical. However, very frequently, the prescription would be in the form of advice on life-style changes. In an idealized world, you would take that advice and implement it.
