Do you guys really think like this or do you just troll for kicks? It just baffles me. Seriously, not trying to be a jerk about it, but REALLY?
Health care professionals have historically only worn masks for very short periods of time and they are never reused. OSHA has respiratory protection rules for industrial folks wearing masks and they are pretty stringent. NONE of what is going on now is comparable to ANYTHING that has gone on in the past.
If you’re a surgeon, anesthesiologist, or operating room nurse doing significant procedures, it’s not just a “short period of time”, and there are folks who do that five days a week for decades.
That should be an excellent control sample.
