and not touching your face with your hands when you're out someplace is one of the easiest things you can do to protect yourself from flu germs.
Have you ever thought about how hard it is NOT to touch your face? We do it like a thousand times a day w/out even realizing it. The way I first noticed it was when I worked as a surgical technologist (several years back). And once you are gloved, you can only touch basically your chest area - cuase that's the only part that is still considered sterile.
When I first started I think I had to reglove at least once a surgery because I would push my goggles up, swipe at my hair under my hat, brush my nose. It was crazy!
Then I worked with my mom in her catering business, and while the standards weren't nearly as strict - I was kind of already in the habit - so I would notcie whenever my hand headed towards my face, or whenver a co-wroker's, then I'd make them go wach their hands.
We just don't even realize how often we scratch our nose, rub our lips, or brush back our hair - because it is such a natural motion.
