I was in Norway for Christmas a few years ago. It was -27 celcius. It was horrifying.
If snow were more common here, or rather if people woke up to the fact that it ALWAYS snows at this time of year, we'd be better off. English houses are typically cold in winter, because a) they weren't well-insulated when built, or b) fuel is so expensive we can't afford to heat the whole house, or c) a combination of the above. The roads get cleared but not very well, and it's illegal to have spikes or chains on your tyres so drivers aren't in proper control of their cars (and we don't get taught how to drive in snow as part of driving lessons, or at least I didn't).
