Writing on medicine practised one person at a time

A small collection of essays by Dr Cindy de Villiers, drawn from the practice's earlier writing and revised for accuracy. They set out the thinking behind Health Function: that useful medicine is worked out for the individual, not read off a population average. They are general information, not medical advice.
