I've never understood the touching/wiping/adjusting of the mask argument. When this stuff first started we heard and read stories constantly that the 2 main things you could do to help avoid the virus were (1) wash your hands often for at least 20 seconds (2) don't touch your face - which was often accompanied by the factoid that studies show the average person touches their face 20 times an hour. So, when mask wearing was not encouraged we were told we needed to discipline ourselves to not touch our faces. If we can be expected to change that behavior, can we not also discipline ourselves to not touch our mask ? I personally can.
The other thing I don't understand is the mask not helping because the particles are smaller than the holes in the fabric. This is probably stupid but here goes - a golf ball will fit thru the holes of a chain link fence easily but if you throw a golf ball at a chain link fence there is a decent chance you will hit the fence and not the hole. Why can't the same be true for a virus going thru a mask? Even if it's smaller than the hole in the fabric, won't some of the particles hit the cloth and not the hole? Especially if you have 3 layers. If you throw a golf ball at 1 chain link fence you might hit the hole and the golf ball make it thru. If you add a 2nd fence an inch behind the first and you line the wire mesh of the 2nd fence up to cover the gaps of the first fence the golf ball won't make it thru. You add a 3rd fence an inch behind the 2nd and you won't be able to get a gumball thru. So, won't some of the tiny virus particles hit one of the cloth layers and stick to it? And is there a benefit to reducing the number of particles that get thru? Or is 1 getting thru as bad as 1,000,000?
