I don’t know if this is a talent but, I know the shape of virtually every country on the planet off the top my head. For example, I know this is Bhutan, etc.
Cool party trick if theres a map around (there never is…)
Theres a game online and in the app store called Worldle. Its like a trivia game for geography where you can test yourself every day. I find it to be a lot of fun! Highly recommend it if you’re interested
