Peradventure have you ever before endured a runny nose? Likely did you eliminate the problem? Of course you recovered! You will not heal a common cold itself, yet your body generally establishes immunity to a specific cold infection within a few days. We call that treated by your personal immune system!

Parents have previously had a great deal of the cold viruses. Parents have established immunity to the colds they have had. Therefore there are not as many cold infections around for parents to acquire. That is why adults only get a few colds each year and children succumb to 10-12 colds per year.
