Maybe have you previously had a cold virus? Perhaps did you do away with it? Of course you got over it! You can't treat a common cold directly, yet your body typically creates immunity to any cold infection within several weeks. We call that treated by your own immune response!

Parents have previously had a great deal of the cold infections. Grownups have established immunity to the ones they have had. So there are not numerous cold infections existing for grownups to acquire. That is why grownups just get a few colds each year and kids acquire a dozen colds per year.
