If you want to test if masks work, do this experiment:
1) Put your hand in front of your face and blow or cough.
2) Put on a mask and repeat.
Did you feel your breath as much with the mask on? No?
Then the mask works. Put it on.
Not wearing a mask is like drunk driving. Odds are you’ll *probably* be fine, but you’re putting yourself and everyone around you at risk, and there is a significant chance you could end up harming or killing them.
It’s just a mask. Put it on.
