"Also using Base 12 for things like clocks, degrees of cirlce etc when we count in base 10 wasn't exactly the smartest of moves either."
Why ever not, Futt Futt; it created the advanced maths concept of duodecimals.
"I'd be surprised if Canadians talk about weather as much as the Brits do, as large land masses like North America have waaaay less weather variation than pokey little islands tend to have."
Have you simply decided to ignore the huge social tool that weather actually provides? How else would you converse with someone you would rather not converse with when escape is no option? With the neutral topic of weather, all guilt, blame, suspicion can be avoided, the necessary social obligations complied with and everybody goes home feeling much better.
Very useful indeed; it has been much warmer here in Spain, but very, very windy. ;-)
