He set out to walk around the world. After 27 years, his quest is nearly over

If he said “I did the math” then he did the damn math, regardless of what country he's from or how you think he should be speaking.

I’ve of course got absolutely zero evidence and you’re taking this more seriously than I’d hoped people might, but I bet he didn’t. Us Brits just don’t say “math”. Or “Legos”.

Of course he may have been indoctrinated by 27 years away from home but I thought it was more likely that he’d been misquoted / adapted for the WP audience.

Anyway, it wasn’t a serious point, just a light hearted one. As you were ;-)
