No doubt you will probably acquire another cold, since there exist 300 different cold viruses. However you will never acquire the exact same cold virus that you had in the past since you have developed immunity to that virus.

Parents have in the past had a lot of the runny nose viruses. Adults have actually established resistance to the ones they have actually had. Therefore there are not lots of runny nose infections existing for adults to become infected with. That is why grownups just get infected with a couple of runny noses per year whereas youngsters succumb to 10-12 colds per year.
