We know several folks who are required to ‘mask up’ at work. No extra breaks to get some unrestricted O2. All of them agree it makes work a LOT more difficult. I feel bad for them but, they need their jobs.
As of today, the death rate in the U.S. is 5.1%.
I and everyone in my company must wear a mask all the day. I wear a mask all the time except in my home. It’s the law.
Wearing a surgical or cloth mask does not make a damn bit of difference to your O2 levels.
