And definitely you will eventually succumb to another runny nose virus, due to the fact that there are over 300 different cold infections. Yet you will certainly never get the exact same runny nose virus that you had previously since you have developed immunity to that virus.

Adults have actually already had a lot of the cold viruses. Parents have developed resistance to the ones they have actually had. Therefore there are not so many cold viruses around for parents to catch. That is why adults just acquire a couple of runny noses each year whereas children succumb to 10-12 runny noses each year.
