Nasser does not speak 7 languages, and graduating from college, on it's own, does not make you intelligent.
I think Flex magazine said 6 not 7. English is like Nasser's 3rd language. He has messaged some getbiggers in German, he messaged El Mariachi in Bosnian, he speaks Arabic when in Egypt in one of his training videos, English (of course), speaks either French or Italian (I cant remember which one of the two now) to Ben Weider in one of this training videos. His mother was Bosnian and father Arabic, and he grew up in Germany, so he learned Arabic and Bosnian from his parents, German and English in Germany, and it seems he picked up on a few other European languages too.
Nasser is one of the few bodybuilders that can speak in-depth about topics outside of bodybuilding - whether its world politics, history, cultures, animals, etc. When we talk usually the topic of bodybuilding or other bodybuilders does not even come up.
