Humoral medicine recognized the individual nature of each person, and modern genetics has begun to do the same. Rather than ground such individualism in unique birth times and astrological data, it bases it on each person’s unique genetic structure—as a component of the mechanical body. Individualized medicine offers a new way to separate the mechanical body from the patient who inhabits it. The expectation is that genetics will identify the inherited propensities of each person to maintain his or her health or to acquire certain diseases. If expectations are fulfilled, then people may be able to avert or defer the onset of some chronic conditions by the medical manipulation of their genetic structure. Chronic conditions like heart disease, type 2 Diabetes, and many cancers have a complex etiology, which includes genetic contributors.
