Masks cut back on oxygen...ask people who hike They trap all kinds of pathogens. When children wear them all day in school; masks have been tested...and an incredible amount of unwanted nasty bacteria have been found. They cause psychological problems in children forced to wear them. They make it more difficult for children to hear what their teachers or others are saying. Forcing people to wear these useless masks is a total infringement on their human rights. If people are stupid enough to go along with the herd...let them do so, but I resent being forced me to go along with information which is not accurate.
