I agree with the DUchenozzle, hand sanitizer is evil. However, not for his reasons but because we are producing a generation of kids that should have been eating dirt, insects (I liked ants) and other nasty germ covered objects but are not. There is going to be and already is a serious medical crisis because kids do not have any immunity to the normal world. Helicopter moms and Purell will prove to be very detrimental to our species.
That's a bit tongue in cheek but basically true.
When in college and trying to solve the mystery of who murdered the two princes in the Tower of London, I had to embark upon an exhaustive study of the Duke of Gloucester, later Richard III (1452-1485; r. 1483-1485), uncle of the two princes.
Richard III had a withered arm and apparently, paralyzed lips.
Most scholars concluded then, and since, that he had contracted polio at a very early age.
But the mystery has always been that polio was non-existent during the medieval era, and so how did this happen?
I dunno how it happened, but with further reading about the history of polio, it appears that lack of good sanitation,
if one survives that, allows one to build up an "immunity" to polio.
And recall when polio was ubiquitous the last century; after circa a hundred years of ever-improving public sanitation.
You
may be a little tongue-in-cheek, but not much.
