And sure you will eventually acquire another cold virus, due to the fact that there are more than 300 various runny nose viruses. But you will certainly unlikely acquire the exact same runny nose infection that you had in the past since you have actually created immunity to it.

Adults have actually currently had a lot of the runny nose infections. Adults have actually acquired resistance to the colds they have suffered from. So there are not so many runny nose infections around for adults to become infected with. That is why grownups just get infected with a few runny noses each year and children usually get a dozen runny noses each year.
