What is genetic predisposition?

Health and sickness are familial, and both often relate back to genetic predisposition. But what is genetics? Basically, genetics and epigenetics study how DNA affects our hereditary sensitivity to diet, toxins, and addictions. So when we find familial patterns of health or sickness, we should assume that DNA is at work, and search for patterns of dietary, toxic, and addictive factors. This will promote health and make us genies of genomics and prophets of proteomics.
