By chance have you heretofore suffered through a common cold? Peradventure did you heal from the virus? Certainly you survived it! You can't treat a cold directly, yet your body generally develops resistance to any type of cold infection within a couple of weeks. That is called cured by your personal immune response!

Grownups have currently had a great deal of the cold viruses. Grownups have acquired immunity to the viruses they have suffered from. So there are not lots of runny nose infections existing for adults to become infected with. That is why parents just acquire a couple of runny noses each year whereas children succumb to 10-12 runny noses each year.
