@wsbgnl It's also impossible for people to keep masks on fully time in many settings such as long distance travel. It is necessary to remove it for hydration, eating, and taking medicine. Lack of universal masking means that the environment in which it is removed is far more hazardous.
@wsbgnl在许多场合，比如长途旅行，人们也不可能一直戴着口罩。为了补充水分、进食和服药，有必要将其移除。缺乏通用掩蔽意味着移除掩蔽的环境要危险得多。
