i wonder if you guys get junkier because you need to be or is it really a bad thing? i like to hear my kids with cf cough cuz i know things are moving...ya know? I live in a place next to the coast and its real humid, my son lives where it is dry and desert like air and he doesnt cough enough so i have heard that there is no real study on this that it is just coincedence.?? i dunno...
