I certainly agree.

Some of my work friends wear the same mask for "weeks", which defeats Its purpose. In fact, due to being exposed to germs/bacteria and the like, It's probably worse than not wearing one at all.

I see that all too often, and those are the people that usually will get in my face and tell me I'm single handedly responsible for the death of humanity for not wearing a mask. I like the concept of "do what is best for yourself and leave everyone else alone"

Hmm, idk how long u should wear one mask...

Let me answer that question:
For surgical (disposable) masks, up to 4 hours, or until it is contaminated by any source (including touching it)
For cloth masks, change at least every 2 minutes. (I'd advise just avoiding them)
KN95 masks, change every hour in a contaminated environment
