How are you going to take off a double or triple mask between bites when you eat or drink, or between puffs when you smoke? It is bad enough when we have to wear one mask and pull it briefly out of the way for this, or to remove one mask to wash up and replace one mask immediately after, or to change one mask. Having more than one mask just makes it that much harder.
And for what? Masks do no good, unless you are worried about dust (or, in the case of the N95, more serious diseases). Why don't people wear masks all the time in New York City for tuberculosis? That would make more sense, because you are dealing with a much worse disease. But for a cold? I personally would rather be somewhat sloppy in "protecting" me against this, along with taking quercetin and zinc. That would allow the coronavirus itself to "vaccinate" me without the shots, wasting all that time, and the dangerous side effects of the actual shots. This means zero masks, either for myself or for anyone else (the quercetin and zinc render the virus about as dangerous as a regular cold, if that).
I will simply wear the one mask where required--and no more. No masks when in a place where it is unlikely to be near other people. No masks when traveling alone (by bicycle or on foot, or alone in a car). No masks on the sidewalk, unless I see congestion ahead where there is a good chance of being within 6 feet of others for a prolonged time (say, a minute or so). No masks when I am at work, and the business is closed for business. If they start making multiple masks mandatory, I will simply get masks that have multiple masks printed on them to look like 2, 3, or more masks. They do no good, and I would rather take my chances with the virus (and my vitamins that make it just about harmless).
