Why Masks And Gloves Will - And Won't Ever - Work

Aesop is a 50,000 watt blowtorch of 'Listen up buster and listen up good!':

"So, if you wear the proper mask, properly fitted, and don and doff it and your single-use gloves, and wash your hands, and don't touch your face, particularly your mucousal membranes (i.e. your eyes, nose, and mouth) with scrupulous attention to detail, flawlessly, from now until whenever, I can absolutely guarantee you'll never get Kung Flu, or most anything else.

But.
You won't do that.
Or rather, some of you won't.
Oh, some of you will, and some will always do it better than others.
And anything 2M nurses can do, you can do.
But a non-zero number of 80-IQ Gilligans will break those asepsis rules, will become Typhoid Marys, get Kung Flu, and asymptomatically carry it to the vulnerable members of society, like they do, and kill 3% of the population, up to perhaps as many as 10M of their friends and neighbors. And that's all it takes to drop a turd in the punchbowl." 

Yup. It's a definite RTWT.
