Perchance have you heretofore suffered through a cold? Perchance did you do away with the cold? Obviously you got over it! You won't heal a common cold directly, but your immune system generally establishes resistance to a certain cold virus within several days. That is called treated by your personal immunity!

Grownups have previously had a lot of the cold viruses. Adults have actually established immunity to the ones they have actually suffered from. Therefore there are not lots of cold infections existing for parents to become infected with. That is why adults just succumb to a couple of runny noses per year whereas kids get 10-12 runny noses per year.
