My question earlier probably doesn't make sense without some more context: as time goes on, words used to describe objects and concepts changes in popular culture. What if this flu continues to escalate for years and everyone is wearing masks 24/7, certainly after a few years of this people would look at that type of mask and think one phrase - 'swine flu'.
I agree it's a stretch at this point but if you are being completely literal about everything there's going to be lost sales. I think erring on the side of trends a bit can only cause a net benefit.
