We are forced to wear one or not pay bills. Wait until you sneeze in one.
About 4 to 5 hours of continuous wear in my shift i start to feel unwell. I usually work 12 to 15 hours.
The big thing people are missing is the recommendation of 3 feet social distancing. Not 6.
Many other countries are doing less than 6. Why are we? There is zero science proving it significantly reduces spread.
