The problem is you don't know if you are infected. The mask using 24/7 is stupid. My thoughts about it is if you are in an area that guidelines can't be followed use the mask , when in area that they can be followed the mask is off. The eight /twelve hours shifts is going to be hard on everyone. If you are infected then less of a chance to infect others, if not better chance of not getting infected. Ether way the cloth or paper mask should only be considered a barrier. It doesn't stop it only controls the chance of spreading.
That's your response, "Fake Science". The extent of the mental gymnastics that some people go through to convince themselves that they are right, and to dismiss information that does not fit into their "concept of reality" constantly amazes me!
