And sure you will probably cave in to a different cold virus, because there are more than several hundred different runny nose infections. Yet you will certainly never acquire the very same cold infection that you had previously because you have actually established immunity to that cold virus.

Grownups have actually currently had a lot of the cold infections. Grownups have developed immunity to the colds they have suffered from. Therefore there are not so many runny nose viruses remaining for grownups to catch. That is why parents only get a few runny noses annually whereas children may get a dozen colds per year.
