Where I work no one has any symptoms. Is it really wide spread?

You don't develop immunity to colds do you?One of the few good things about getting old is that during your lifetime you have become immune to most of the cold viruses, so you're rarely affected/infected
No. They are generally new seasonal variants so you don't develop immunity by exposure.You don't develop immunity to colds do you?
I think there is over 200 different strains of the cold virus so once you get one and recover you will develop some immunity to that strain but then there are shed loads of other strains that can infect you. As time goes by your immunity to the strain you caught will weaken and good chance you may catch it again at some point in the future.You don't develop immunity to colds do you?
You will be immune to the specific cold viruses that you have had before, but yes not the new variants although you will have some immunity depending on how different they are meaning you won't be affected as badly. New variants will still have some antigens recognisable by the immune system.No. They are generally new seasonal variants so you don't develop immunity by exposure.
You can improve your general immune system through lifestyle (diet, fatigue, fitness for example) though or it can be weakened other ways (smoking, vitamin deficiencies, underlying health conditions etc).
I would suggest if RH doesn't catch colds as often as he used to, it is probably down his lifestyle leading to an improved immune system or reduce exposure to environments where he is more likely to catch one.
