Amazing how clueless some people are.
Airborne is simply a glorified multi-vitamin, with extra Vitamin C.
Couple years ago, one of my co-workers was flying to Houston. She wouldn't shut up about Airborne. Telling everybody she *has* to take Airborne, otherwise she gets sick when she travels.
So I looked at the label and said "What's the big deal? Almost the same as my daily multi-vitamin." Then I showed her the label on my multi-vitamin.
You'd think I told her Santa Claus didn't exist.
