Hey Marki- Not sure if this is still something you’re considering, but I know in my experiences with cultural diversity, sports has been a major influence. Now this may not apply to you if you have no interest in athletics, but some of the most diverse situations I’ve found myself in involve soccer (futbol) and basketball. I’ve even been in, and totally enjoyed myself, situations where I (or others) didn’t even speak the same language, but somehow managed to come together and “be on the same page” while on the field/court. Athletics seems to be one of those things that brings people together… and the Olympics are coming up, so that’s something you could consider as well. Good luck!
