@DarkTrig @Bob_Wachter Safe in the real world is almost always a matter of degree. "Safe" vs. "unsafe" is usually false framing by someone with an agenda (or poor understanding).
Others w/n95s are more safe if you and others avoid spewing virus in the air. But w/no mandate, you are "allowed" to spew.
@DarkTrig@Bob_Wachter在现实世界中的安全性几乎总是一个程度的问题。“安全”与“不安全”通常是有议程（或理解力差）的人的错误框架。
如果你和其他人避免将病毒喷到空气中，其他带有N95的手机会更安全。但在没有授权的情况下，你是“被允许”吐的。
