oh wow an M.D. says something, I'm so impressed /sarc.He is an M.D. , just sayin, Not an optometrist. Gives him a little bit more cred in the disease game than, oh I don’t know, – – YOU.
I think if one has medical issues it makes sense to seek professional opinion of course. But also everyone knows there are quacks out there and some of them have an M.D. If you don't have a skepticism radar up for that, I don't know.
I don't think anyone is silly enough to take actual medical advice from people just casually posting here, who don't have and make no pretense of medical expertise. I mean casual stuff is just that, it's casual opinon, it's not professional expertise. But that said ... with a serious medical issue I wouldn't advise anyone to rely on the opinion of a single M.D. unless it's an emergency and urgent action is needed. Always get a second opinion from a second doctor.
And what is it even about? I think the authorities should have LONG SINCE pivoted to talking about mask quality, KN95s became available before N95s. I mean obviously they should have. But local authorities could never even distinguish between indoor and outdoor risks long before Delta (to what extent that still holds with Delta, well probably but Delta is more contagious if unvaccinated). So communication has been bad, head bangingly bad. And initially availability of masks was bad, and maybe we should try to prevent that in the future.
