And of course you will eventually succumb to another cold, since there are more than several hundred different runny nose viruses. But you will certainly never ever acquire the exact same cold virus that you had previously because you have created immunity to that particular virus.

Grownups have previously had a great deal of the cold viruses. Parents have actually developed immunity to the ones they have actually had. So there are not so many runny nose infections existing for grownups to become infected with. That is why adults only succumb to a few colds each year whereas children usually get 10-12 runny noses each year.
