Re: Nothing to Heil nothing to Fear.
I saw that research model (without the spelling mistake) and my first thought was that it was a worst case scenario, ie scare mongering. Yes it *could* happen, but most people cough into something, hand, handkerchief, tissue, sleeve etc. They didn't produce any nice animated graphics for those more normal situations. If that had done that research and compared the results, I'd have more respect for them since it would help drive home to people *why* they need to be careful instead of instilling yet more FUD.
