Ever wonder how we know what we know? Especially in medical research? How do we know that some diets are probably more healthful than others? How do we know that smoking is likely to cause lung cancer? You might be surprised to learn that it's not all about scientists doing experiments in labs. Much of what we know comes from population sciences. And epidemiology is the mother of all population health sciences!

Nothing To Do With Skin is an introduction to the science of population epidemiology, written by a well known, award winning, senior epidemiologist.

All of this is done without any mathematics. This is truly an entry point for either a curious layperson, or a science or medical student wanting a little extra guidance on this most transformative of fields.
