Finally, scientific proof that wearing a mask can be bad for your health even if you don’t catch the Chinese Communist Party Virus. Explains why I almost passed out the first time I wore one for an extended period at the grocery: lack of oxygen in the blood and buildup of carbon dioxide in the blood.
Of course you can’t get into a grocery or most other stores without wearing one and for liability reasons it’s doubtful these studies would persuade a store manager to step out of line. So, take deep breaths before and after shopping. And don’t just browse. I cheat and lift it for a breath when no one’s looking.
