Not that I watch FMA or anime for learning something new.
After all the "research" I did on internet of FMA (blame the obsession xD), I wouldn't know that FMA had so much to do with Germany until then. And since I didn't choose the subject history, I had no idea about the Zeppelin stuff and World War except from other really basic fact bout Hitler, Stalin, bomb in Hiroshima etc xD
And indeed, I watch anime for fun, but sometimes I do surprisely learn some fact or new words. Or else, the way Edward (and other characters) thinks and behave was rather fun to observe with psychological in mind, plus philosophy, which eventually turn into Theory of Knowledge (I hate this subject O_o). Well, Sci fict stories somehow tell me how to get over bad things and how to keep on going forward ^__^
