A classic, if apocryphal, medical student story: to reinforce the importance of hand washing, a group of students were given a small amount of oatmeal that was laced with something that glows with UV "black" light. They were told to be sure and wash their hands before patient contact. Each passed an initial screen with the light to assure it was negative right after ingestion.
48 hours later, a team went in to inspect the patient rooms with a black light. There was feces everywhere. EVERYWHERE. Sheets, patient pillows, the ceiling (!), floors, faucets, door handles, their stethoscopes, hands, and their genitals.
We live in a world of, uh..., enteric flora in my job, and it's not much better in restaurants. Then again, most of our exposure, by a factor of thousands I'd guess, is the stuff we carry around in our bodies all the time.
) we are now tentatively planning to put off this move to Missouri for at least a year or two because of the housing market. A house near Franks that we are famliar with went on the market this week for a disgustingly low price and we are fed up! That was the Last Straw.
