Seriously, why is hand-washing after using the bathroom such a big deal? I’m not in the habit of getting urine or poop on my hands (and urine is sterile, isn’t it?). My crotch isn’t any less sanitary than my arm pits or my feet, yet nobody demands that we wash our hands after applying deodorant or removing our socks at the end of the day. The surfaces within the bathroom are used far less than the hand rail of the staircase or the button on the copy machine or even the front door of the office, yet we aren’t required to wash our hands after touching any of those surfaces.
I distinctly remember an experiment that we did in my high school science class where we walked around the school and took samples of different surfaces to see which ones had the most germs. In every case, samples taken from the bathroom always had fewer germs than samples taken elsewhere. I also remember an episode of Mythbuster’s where they were trying to figure out how much fecal matter accumulates on a toothbrush in the bathroom. As a control, they placed a second toothbrush in a jar, far away from any bathrooms. At the end of the experiment, the toothbrush from the jar had just as much fecal matter as the toothbrush from the bathroom (a minuscule amount), showing that fecal matter isn’t somehow accumulating on bathroom surfaces.
Does anyone know the answer? Perhaps references to studies that show that people who wash their hands are healthier than those who don’t?
