And sure you will probably succumb to a different cold, since there are over 300 different runny nose infections. But you will unlikely acquire the very same runny nose infection that you had previously because you have created resistance to it.

Parents have actually currently had a great deal of the cold infections. Grownups have acquired resistance to the colds they have actually suffered from. Therefore there are not numerous cold viruses existing for parents to become infected with. That is why parents just succumb to a few runny noses per year whereas kids acquire 10-12 runny noses each year.
