I don't know what it is...apparently something in the air but the last couple of days I've been sneezing, and have a scratchy throat, been blowing my nose ALOT lately. I think I need to get one of these ...what do you think???? I will no longer be running around looking for a Kleenex in hopes to get it before that sneeze comes out..and heck next time Im in a public bathroom I wont have to worry if the stall I choose is out of toilet paper!!!! If nothing else I bet I get a few looks with this strapped to my head!!!
