Perchance have you a while ago suffered through a common cold virus? By any chance did you do away with it? Of course you recovered! You can't heal a cold itself, nevertheless your system generally establishes immunity to a particular cold virus within several days. That is called cured by your personal immunity!

Adults have already had a great deal of the cold infections. Adults have actually established resistance to the viruses they have actually suffered from. So there are not as many cold infections remaining for grownups to catch. That is why adults only succumb to a couple of runny noses annually and youngsters succumb to 10-12 runny noses each year.
