No doubt you will probably get infected by an additional cold, because there exist more than 300 different runny nose infections. However you will unlikely get the same runny nose infection that you had previously due to the fact that you have actually created immunity to that particular virus.Grownups have actually currently had a lot of the cold infections. Grownups have developed immunity to the viruses they have had. So there are not lots of cold infections around for grownups to acquire. That is why parents just get a few colds each year and kids get a dozen runny noses each year.
