And of course you will probably cave in to one more cold virus, because there remain 300 various runny nose viruses. However you will never ever get the very same runny nose virus that you had previously since you have actually established immunity to that cold virus.

Parents have already had a great deal of the cold viruses. Parents have actually acquired immunity to the viruses they have suffered from. Therefore there are not lots of cold viruses around for grownups to become infected with. That is why parents just succumb to a couple of runny noses each year and kids get 10-12 colds per year.
