I have a friend living in Florida who from time to time sends me weird, funny, interesting stuff she happens upon. Today, her mail included two maps:
This map points out in red all countries that don’t use the metric system.
And this one indicates in white the 22 countries never invaded by England.
One should think, the two would correlate more, but oddly, they don’t. I never even realized, Britain changed to the metric system. Neither did the Brits, though, still speaking in yards, pints and so on…
