>>certain groups (nurses, doctors or certain workers) have to wear a masks all of the time for years Not really - doctors/nurses etc have for a very long time worn masks for short periods of times, for certain procedures, for certain hours of the day for some days in the week- very few HC professionals have ever had to wear masks continually all day long, day after day and then also for additional chunks of time as they go about their non-work life.
