And sure you will probably acquire another cold, due to the fact that there are more than several hundred different cold infections. But you will certainly never ever acquire the very same runny nose virus that you had in the past because you have actually developed immunity to it.Parents have actually currently had a lot of the cold infections. Grownups have developed resistance to the viruses they have suffered from. Therefore there are not quite as many runny nose infections existing for grownups to acquire. That is why parents just get a couple of runny noses annually and kids usually get 10-12 colds per year.
