I have been wearing a homemade mask when I go out. I understand the studies say they work... But man I am pretty sure my breath is just going out around all the edges. My sunglasses fog up as I'm walking into the store. And when I take them off, my breath is just going up around my face at a higher velocity. I guess it's not going towards other people though... the more I read, the less I know about this shit.
