By any chance have you once suffered through a common cold? Peradventure did you heal from the infection? Certainly you got over it! You can't cure a cold itself, yet your immune system typically creates resistance to a particular cold virus within a couple of weeks. We call that being healed by your very own immunity!

Parents have currently had a lot of the runny nose infections. Parents have actually established resistance to the ones they have had. So there are not as many runny nose viruses around for parents to acquire. That is why parents only succumb to a few runny noses per year whereas youngsters get 10-12 colds each year.
