I know, i use to wear the same masks while wood sanding and cutting dry wall as well as cutting concrete, face was still covered with the dust after removing the masks and covid19 is 10 times smaller.
Wore masks at multiple jobs.
Sanding paint , foundry work,winding room with talcum dust in the air.
A well fitted mask didn't leave evidence of dust in nose or on covered areas.
Oh yes , improper fits were obvious on peoples faces.
Respirators when in paintbooths ,or pumping/transferring acid ect. let a wearer know pretty quick if fit was not secure...Did me anyways.
Masks will not eliminate covid virus.
The purpose of wearing them is an attempt to reduce potential spread.
If that reduces gobs of sputum on other people and objects , great.
The problem seems to be folks who are able to spread it , that are unaware they have it already.
My smokers cough. Someones allergy inspiring a cough. Is going to launch more than someone breathing through their nose at rest.
But is that nose breather not capable of spread?
In exchange for a worse case gamble of masks not reducing spread , we get the inconvenience of wearing them in stores and public settings of close quarters with others.
Of all the societal crap we endure , masks should be the least of our complaints as to effectiveness of improving a society's well being.
It's simply citizens not trying to share a tricky (as far as knowing if you are capable of spreading it at a given moment by being a carrier early on) virus deliberately with other citizens.
A local ol gal the community keeps an eye out for was in the restaurant yesterday. "We" keep her tab covered so she has a place to grab a bite at ease.
Past the century mark she may be expected to be vulnerable.
Patrons tolerate masks to and from tables and spread out from others.
She left without a mask and no one said a peep. Did anyone resent masks ? Or complain of potential effectiveness? Or of her ?
Nope. Not out loud if they did.
I'm willing to wager no one would want her to catch covid from them if a mask not worn by them could be attributed.
Maybe a mask does not reduce spread as much as hoped.
I'll take my chances around the vulnerable.
Meanwhile the ladyfriends family has had multiple members catch the virus down South.
And my family/inlaw kin invited friends up from Florida to the lake , to end up testing positive and heading back home.
After all complained about not being able to visit inside a care facility for a senior...
It spreads. Any reduction among the vulnerable is/would be worth it.No matter how healthy we ourselves are, or our opinion of the effectiveness of masks..
