so, i saw the article talking about the airblade spreading germs before, but upon re-examination it seems a bit weird. They dipped their hand into water with a harmless virus (as a stand in for a dangerous virus), but isn't the whole point of washing your hands is to wash them with _clean_ water. Water coming out of a faucet is likely chlorinated and free from contamination. Right? Just seems odd. FTR, as cool as the airblades are, I have meat hooks for hands and have about .5 cm of clearance on either side when I use one, so I almost always bump into it. I'll use paper towels if I can. Either way, the Hygiene Hypothesis (https://en.wikipedia.org/wiki/Hygiene_hypothesis https://en.wikipedia.org/wiki/Hygiene_hypothesis) seems very reasonable to me, and while I haven't studied it in depth, ancedotally it seems to ring true.
