Maybe have you ever suffered through a common cold? Perhaps did you do away with the issue? Obviously you did! You can not cure a runny nose directly, but your system usually establishes resistance to any cold virus within several weeks. We call that cured by your own immunity!

Parents have previously had a lot of the cold viruses. Adults have actually created resistance to the colds they have actually suffered from. So there are not as many runny nose viruses around for adults to become infected with. That is why grownups just get infected with a couple of runny noses annually whereas youngsters usually get 10-12 runny noses per year.
