I honestly don't care if they work or not. I've gotten used to wearing one and it's no longer an inconvenience to me. I'd rather wear one than get stank face looks from other people while out in public. When it comes down to it, there is a whole lot that we don't know. With every scientific study that comes out, a new one will come out the next week refuting it.
I can't tell if people are giving me the stank face or not when they're wearing a mask. All I ask is don't stank face me with your mask on. I need to know who is stank facing me so I can remove my mask and stank face them back.....damnit. 😹
