Possibly have you heretofore been down with a cold? Peradventure did you recover from the cold? Of course you got over it! You can't cure a runny nose itself, but your immune system generally establishes resistance to any cold virus within a few weeks. We call that being healed by your very own immune response!

Parents have in the past had a lot of the rhinitis infections. Adults have acquired immunity to the ones they have had. So there are not numerous runny nose viruses around for adults to catch. That is why parents only get a few colds per year and kids usually get a dozen colds each year.
