No doubt you will eventually succumb to an additional runny nose virus, since there remain several hundred different cold infections. Yet you will unlikely acquire the same runny nose infection that you had previously because you have created resistance to it.Adults have in the past had a great deal of the cold viruses. Parents have acquired immunity to the viruses they have actually had. Therefore there are not quite as many cold viruses around for adults to become infected with. That is why parents only succumb to a few colds annually and kids succumb to 10-12 colds annually.
