Possibly have you previously had a cold? Likely did you get rid of the virus? Naturally you recovered! You won't cure a common cold directly, yet your body generally develops resistance to any type of cold virus within a few weeks. We call that cured by your own immunity!

Parents have previously had a lot of the rhinitis infections. Grownups have actually developed immunity to the colds they have had. Therefore there are not lots of runny nose infections around for adults to catch. That is why adults just get a few runny noses per year and youngsters get 10-12 colds each year.
