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:

maps_no metric system
This map points out in red all countries that don’t use the metric system.

maps_never invaded by England 22
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…
