As long as I am taking Prednisone I will continue to mask in crowded and/or poorly ventilated public buildings, particularly as long as COVID continues to be a thing. Basically I only go out to shop for groceries/necessities. It’s easy to manage since I’m retired, but it still severely limits having any social life (restaurants, movies, etc.). I also refuse to travel in any vehicle (plane, train, bus, etc.) other than my car.
