“Medical workers don’t wear them all day, everywhere - just in certain patient contact situations. “

Even if that were the case, you’d still have thousands of surgeons and their OR staff dropping dead daily. Surgery can take many hours and the those in the OR are required to wear masks. For such persons, it’s 8 hours (usually much more) a day work, 5 days a week.
This isn’t to say anything if masks are helpful or not in the covid situation, that’s a whole different question.
Just that, experientially and logically, we’ve had a century of experience of people wearing masks for prolonged periods of time through the years without mass causalities occurring. It’s not a hypothetical.
1) This says this study “suggests”... I stopped reading right there!
2) Masks Do NOT stop this virus
3) You want to wear one, be our guest, but don’t be snarky and imply we should all just shut up and wear these ridiculous masks!
4) They do indeed restrict your oxygen intake!
You’ve never been in an OR, have you?
