problem is it dont make sense ! can you get covid if you hold your head underwater for a long period of time ? how about a pillow over your head? percentage is the best part (2 masks equal 75% effective) yet (3 masks equal 90 % effective) lmfao ….. you’d think (1 mask 25 %) (2 mask 50 % ) (3 mask 75%) (4 mask doesnt matter your probably dead at 2)
