Used to use alcohol (basis of hand-sanitizer effectiveness) to sterilize in hospitals (before autoclave). Had to soak for 20 minutes in pure alcohol. What difference can rubbing dilute alcohol onto your hands for 3 seconds do?
There might be a difference in how thoroughly you need to sterilize something (1) before bringing it into prolonged contact with someone's bloodstream, internal organs, etc., versus (2) before briefly touching your food / blowing your nose / ... with it.
No, no difference really, if your goal is to avoid transmitting a virus.
Yes there is. It's like the difference between going to Volgograd as a tourist today and going to Stalingrad as a member of the German army in the winter of 1942-43.
Ah, a simple metaphor we all can relate to. :)
Yeah, if I had been saying it out loud I would have been grabbing for words halfway through and would have realized it was a bit overwrought.
