Health is the result of biological and social determinants; both are important. Nature dictates the laws for biological determinants; people create the laws for social determinants. Nature's laws are hard to discover and are eternal whether or not they suit humanity; people's laws are easily written and can be changed at anytime to suit humanity better. So why is it that the public health community, which expends much effort and expense probing natural laws, places negligible emphasis on collection, analysis, and making greater use of the world's public health laws?
