And of course you will eventually cave in to a different cold, since there remain more than 300 different cold viruses. Yet you will certainly never get the very same runny nose virus that you had in the past since you have developed immunity to that cold virus.

Adults have in the past had a lot of the rhinitis viruses. Parents have actually developed immunity to the colds they have suffered from. Therefore there are not so numerous of cold infections existing for parents to acquire. That is why grownups just acquire a few runny noses annually whereas children acquire a dozen runny noses per year.
