Why can't we cure the common cold?

First of all, common cold? Are there posh colds? Bear with me, all I've been doing for the past couple of days is reading, pondering sleeping and coughing. Stupid little asides like that keep popping into my overheated brain. Today, thanks to some meds for a 'severe' cold (I wouldn't call it severe but then it wasn't 'common' either)I'm vertical instead of horizontal.

However the question remains, our scientists can put a man into orbit, they can cure certain genetic diseases, what's a pesky little viral infection to science? And a cold is a virus which is why antibiotics won't help because antibiotics treat bacterial infections.

I prefer a natural approach but sometimes you have to wheel out the big guns so when two days of steaming, hot honey lemon and ginger and salt gargles didn't help, I went the drugs route. Of course I went roaming around the internet before writing any of this. I came across several interesting sites, links are below. I also came across the reason (I think) that I caught whatever it was. My smartphone use has gone through the roof.
