And definitely you will eventually get one more cold, because there are several hundred various runny nose viruses. But you will unlikely get the very same runny nose infection that you had in the past since you have developed immunity to that particular virus.

Parents have previously had a great deal of the rhinitis infections. Grownups have developed immunity to the colds they have suffered from. Therefore there are not lots of cold infections around for adults to acquire. That is why adults only get infected with a couple of runny noses per year whereas kids succumb to 10-12 colds per year.
