A history of hand-washing -- and good reason to continue the practice.
In theory, bacteria probably could evolve resistance to bleach or isopropyl alcohol.
Two guy walk into the restroom to use the urinal. Afterwards, the first guy notices that the second does not wash his hands. The first guy says, "My parents taught me to wash my hands after using the bathroom." To which the second guy says, "That's nice. My parents taught me not to pee on my hands."
People, you do realize that the hands are the part of the body (excluding the mouth and the rectum) that harbor the most bacteria? In a public restroom, the doorknob is dirtier than the toilet seat. Regular hand washing is the easiest way to spread common infectious diseases. There is a good reason that, in a hospital, the rules are 1)cover your mouth when you cough, 2) don't touch your face, and 3) wash your hands. It's not germophobia. It is a simple and prudent health measure. The More You Know...
This was an outbreak involving a commercial airline with 5 crew members and 49 passengers delayed in Homer, Alaska for 4.5 hours, including 2-3 hours when the ventilation system was turned off. An acutely ill patient with a new influenza A strain stayed on the airplane, and 72% of the crew and passengers subsequently became ill.
You don't have to be Monk (or a compulsive nose picker) to recognize that basic hand hygiene is not the same thing as phobia. How many things have you handled during a day that were probably handled by fifteen or twenty people before you that day? And probably not sanitized in weeks or months, if ever? And then a speck of dust gets in your eye and you rub your eye without thinking twice...
That's why I lick doorknobs.
