In sickness and in health care: a student's thoughts before beginning his medical training.

This essay is a "prespective"-the musings of a soon-to-be MD/PhD student on various aspects of the practice of medicine, written just before he began his training in the fall of 2008. It discusses some of the issues-genomic medicine, healthcare reform, and evidence-based medicine-that will likely impact medicine and medical care during his career. These thoughts are interwoven with the personal story of his grandfather's fight against disease and the complications of diagnosis and treatment.
