Likely have you hitherto had a common cold virus? Perhaps did you get rid of the cold? Obviously you got over it! You cannot heal a runny nose itself, yet your system generally develops resistance to any cold infection within a few days. That is called being healed by your personal immune system!

Parents have actually already had a lot of the rhinitis viruses. Parents have acquired resistance to the ones they have suffered from. So there are not as many runny nose infections remaining for adults to acquire. That is why parents just get a few runny noses annually and youngsters get a dozen colds each year.
