Health Care workers (at my place) have been wearing them for up to 13 hours straight for going on 18 months now. I have my own pulmonary issues and frankly, it was worth it to me to just walk away a few years early, much sooner than I had long planned.
I am not the only one. Word is that in 6 months my entire old department has been replaced with new younger workers, save a few.
I don’t blame you at all. I retired at 58. I think one reason they don’t bother me is after wearing the N95 for so long these are easy. I’m retired now so I never have one on longer than a few minutes and only if a business asks us to. My granddaughter is in the medical field and even though she has been trained in wearing them, none are healthy for extended time.
If the ivermectin works I won’t be wearing them anymore.
