You also use "stone" and "furlong" in certain contexts and drive on the left side of the road. I think it's awesome and makes the UK unique in some regards. It's what culture and customs are all about.
In the 40+ years I've lived here I've only ever heard furlong used in the context of horse racing and the actor that played John Conner in Terminator 2...
Re the driving - about 35% of the world are on the left!
There is more than one way to lead your country back into the late neolithic, just go on.
