Open the doors, open the windows, and let the fresh air flow inside the room.
With some towns in N.H. requiring masks for indoor activities like public meetings, public school class rooms, and public community athletic games, it don't hurt none to open the doors.
Just let that fresh outdoor air flow inside the room to help alleviate the risk for catching the virus. Just take a breath, and it's spring time, cough-cough-cough, gaag .....awg ...... must be another case for contracting the virus. .....

.... cough-cough!
