Being born in Brazil, having lived in the US and currently living in Japan, I can speak Portuguese, English and Japanese.
Apart from that (I don't mean to show off or anything), due to the fact that the study of foreign languages plays a huge part in my area of research (Philosophy), I can also use Spanish, French, Italian, Ancient Greek and Early Medieval Latin. Finally, I've studied German and Hebrew in during my time as an undergrad student, but I have some difficulties in writing and speaking them nowadays.
I really wish I could understand Russian and Chinese though...
