Probably have you a while ago endured a cold virus? By any chance did you eliminate the issue? Certainly you did! You cannot treat a cold itself, yet your system normally establishes immunity to any cold infection within a couple of weeks. That is called being healed by your own immunity!

Parents have actually previously had a lot of the cold infections. Grownups have established immunity to the viruses they have had. So there are not as many cold infections existing for adults to become infected with. That is why adults only acquire a few colds annually whereas kids acquire a dozen colds annually.
