Mask do NOT work! No one will ever believe me, but think about it. I am a retired nurse of 38 yrs and have only worn a mask 4 times since all this mess has started, only because I didn't have a choice. When you wear a mask and someone coughs, then all of the material goes between the mask and you and stays there. Without the mask, the wind blows it away. Why do you think all the 39 states have increased since mandatory mask. No one in my 32 unit apt complex wears masks and no one is sick. I'm sure the drs will think I'm crazy but in my 38 yrs I've seen alot of medicine do the reverse. You never know till you try it!
