Perhaps have you hitherto had a common cold? Perchance did you recover from the cold? Certainly you survived it! You will not treat a common cold directly, nevertheless your immune system generally develops immunity to a certain cold virus within several weeks. We call that cured by your own immune response!
Grownups have actually already had a great deal of the cold infections. Grownups have acquired resistance to the viruses they have actually had. Therefore there are not as many cold viruses around for parents to acquire. That is why adults only get infected with a couple of runny noses per year whereas kids acquire 10-12 runny noses each year.
