And of course you will probably get an additional cold virus, because there exist 300 various runny nose infections. But you will unlikely acquire the same runny nose infection that you had in the past due to the fact that you have actually created resistance to that particular virus.

Parents have currently had a lot of the rhinitis infections. Grownups have actually established immunity to the viruses they have actually had. Therefore there are not quite as many cold infections remaining for grownups to catch. That is why parents only acquire a few runny noses per year whereas kids usually get 10-12 runny noses each year.
