Who decided that Vit C is good to fight colds? Linus Pauling? Sure he could tell ya all you want about bond valences but he didn't do that much research into Vit C. He did say, though, that taking 1 gram a day will decrease the incidence of colds by 45%. How precisely will that help someone who is already sick?
Maybe if I sneeze hard enough I'll dislodge the microbes.
I wonder of Roc Ordman had a thing for Pauling.
