Really? Then I guess your neurosurgeon - who wears one for HOURS - day after day - and his entire surgical team - is IN BIG TROUBLE!!!!!! You better NEVER let a doctor operate on you EVER AGAIN because they must ALL be suffering from brain damage - because they all wear them ALL THE TIME - for HOURS AT A TIME!!!
I guess millions of Japanese people - who have been wearing them for YEARS - are all suffering from O2 deprivation - because they wear them - well - even when they aren't sick.
I guess all those nail salon ladies who wear them for 8-10 hours a day - day after day - ARE IN BIG TROUBLE!
I guess all those tens of thousands of woodworkers - fiberglass workers - etc - that wear them ALL THE TIME - are in BIG TROUBLE!
SMDH - the stuff people believe and don't actually think through - is MIND NUMBING. Common sense has TRULY left the freaking building.
What bugs me the most are the mask shamers.
