Some people, like me, hate wearing masks. I wear glasses and I have hearing aids. When I take that stupid mask off one of my hearing aids likes to fall on the ground. Anyway, we breath in nitrogen (78%) and oxygen (21%) which is good. Breathing out pushes out the same elements with some water droplets. I don't relish breathing in the same air again. Besides that if you have hearing aids it gets pretty frustrating trying to figure out what some people are saying "mumbling" behind their masks. I can't read lips when there are no visible lips to read. No, wearing a masks is not WONDERFUL for me. Maybe the 20 year old like it; I don't know!
