Fellas, the main issue is not how the flu gets passed on from host to host. Main issue right now is that we're reaching pandemic proportions every year now. Virus-wise, we're at a crossroads in terms of it spiraling out of control (mutating too fast for us to develop a workable vaccine, a battle we're about to lose soon) or it will develop so quickly that even when vaccines work (albeit marginally,) the flu season will get longer and we will reach pandemic proportions right after summer.
Either way, everyone WILL have to deal with it. I, for one, cannot understand how smoking is prohibited in enclosed spaces but sneezing a potentially fatal illness isn't.
Either way, we're f*cked.
