Maybe not, but the wearing of masks does affect our brains, IMO. Masks, primarily forced on us by liberal politicians, causes us to breathe in more of the CO2 that we should naturally be exhaling. This, in turn, reduces our ability to absorb oxygen, and of course that decreases our brain function.
The libs want people to be as scared, miserable and stupid as possible until after the election, so look for masks to be required in areas controlled by Dims until November 4th.
