I looked up from my computer to motion the next patient in line and saw before me an elderly gentleman who resembled many of the other patients attending our health fair in Key West. Casually dressed: a white V-neck T-shirt and track pants. Hair: gray and wispy. Skin: tan and leathery from the sun. He was over six feet tall, with an athletic build for a man his age. It was approaching lunch hour and the line for my Med IT station was dwindling.
