Oh wow, I don't think I've ever heard of air born medication. What'll they think of next? I remain utterly convinced that if it doesn't get thought up in this day and age, it just won't be thought of. Technology has reached that point. Next thing you know somebody out there who's smarter than I am will figure out a way to make physical time travel a reality, and we'll be doing it from our own living room if we want. Hey, I can dream can't I? *laugh*.
