And of course you will possibly succumb to a different cold, due to the fact that there exist 300 various runny nose infections. But you will never ever get the same runny nose infection that you had in the past because you have actually established resistance to that particular cold virus.

Therefore there are not so many runny nose infections around for parents to catch. That is why adults only acquire a few colds annually whereas kids succumb to a dozen colds per year.
