thank you! when public service health announcements occur, they are not just someone's whimsical idea. they are always based on scientific evidence of an empirical nature (testable, verifiable, replicable). not to say evidence can't be wrong or made better through re-testing, but PSAs aren't just hare-brained schemes. they are based in the best evidence available at the time.
i know we all like to think the gov't knows nothing and we shouldn't listen to a word they say, but really...this makes perfect, legitimate sense from a public health standpoint. if it seems gross, fine. better gross than contagious. i prefer gross that i can see but is contained to contagious (but invisible). we americans are so odd about things sometimes.
I think whats getting lost here too is that were not saying people should BLOW THEIR NOSE into their sleeve, there is a difference between a sneeze and a snot rocket. If your nose is running, go blow it, if your in the line at old navy and need a quick sneeze you sneeze into your elbow, then politely excuse your self, go to the bathroom and blow your schnozzle. This gives you a way to wash your hands. People are making it sound like the PSA's are about walking around with bogeys dribbling down your sleeve, this is not so. However little kids, no matter how well you train them, will inevitably be little snot balls at this time of year. And yes purrell is not idiot proof. Read the data, even handwashing is uneffective if the right amount of friction and time are not used. If you understand ANYTHING about portals and vectors, drying your hands out to the point they crack just creates a portal for infection, I say good luck with that. Not to mention the endless studies on how antibacterial products can adversely effect things like resistance.
