Yeah, removal of all germs is not something I would ever be interested in. I'm keen to keep a strong immune system, thanks.

Having said that, I'm also not keen to aerosolise and breathe in whatever's on the hands of the ten people who used the hand dryer before me. I like the hand dryers that blast a decent flow of warm air past your hands towards the floor, rather than an extreme flow of cold air past your hands at a pool of other people's used hand-washing water.
