What causes disease? What can we do to improve our health?
Modern medicine’s answer to these questions lies in its understanding of the human body as a complex machine. Like any mechanical contraption, the body is bound to break down. Doctors serve as specialized mechanics who wield sophisticated tools and procedures to address our malfunction. They can numb our pain, carve out and radiate our cancers, trigger or suppress our immune systems, recalibrate our neurotransmitters, and they may soon be able to retool the genetic flaws thought to be the progenitors of disease.
