Do you have statistics to show that to be true?
Any numbers of the people who die shovelling out their grain bins with masks on? breathing all that CO2.

I was just reading this article before clicking on this so went back to get a link for you to look at.

Policies on masks are one of the factors differentiating states like Texas from those seeing lower transmission rates. 

In 11 states with mask rules in place - including New York and Illinois - the number of new cases has declined 25% in the last two weeks, according to an analysis by the Philadelphia Inquirer. On the other hand, in states where only some employees have to wear masks, new cases have risen by an average of 70%.

I will follow the link to the Inquirer to see what it says.
