And sure you will possibly cave in to one more cold virus, due to the fact that there are over 300 different runny nose infections. But you will unlikely acquire the very same cold virus that you had before because you have actually established resistance to it.

Grownups have currently had a lot of the runny nose viruses. Grownups have developed immunity to the ones they have actually had. So there are not as many runny nose viruses around for parents to acquire. That is why adults only succumb to a few runny noses each year whereas kids succumb to a dozen runny noses per year.
