In the future, can we get DNA tests as children to find out what types of diets to eat and what kinds of medicine to take? If only it was that easy. A new study suggests that, for most common diseases, genes alone only tell part of the story–and the environment tells the rest of it, because it interacts with DNA in ways that are difficult to predict.
