Wearing a face mask for hours on end is extremely unpleasant. The moist heat that builds up around the mouth is intolerable in any environment that isn’t fully air conditioned, that includes most of the situations we find ourselves subjected to in Airports and aircraft pre and post Departure until Arrival. Infections around the face will increase as a result. Passengers and Crew will just not tolerate this “new normal” for very long, if at all.
