Those colds that you’re seeing represent common symptoms of many viruses (metapneumovirus, paraflu, influenza, rhinovirus, RSV, etc, etc ... and many of these have multiple subtypes which can be concurrently circulating). In other words, you’re noticing common symptoms not necessarily the same virus.

And not just that. I have a septum deviation, so I basically have a runny nose all winter long, even though, most of the time, no viruses are involved.
It's worth fixing that, surgery has come a long way. I had it surgically corrected last year and the energy boost from better breathing while physically active, better sleeping, and the lack of annoying people with my snoring are well worth it.
