Peradventure have you heretofore endured a runny nose? By chance did you heal from the cold? Naturally you survived it! You can not heal a runny nose itself, but your body usually creates immunity to a certain cold virus within a couple of weeks. We call that cured by your very own immune system!Parents have actually already had a great deal of the cold infections. Parents have actually acquired immunity to the colds they have actually suffered from. So there are not lots of runny nose infections around for parents to acquire. That is why adults just get a few colds each year whereas kids usually get a dozen colds per year.
