So, I am curious.... There is correlation between learning a second or more languages and intelligence. It makes you smarter, better critical thinking skills, better concentration, memory, and listening skills. In the US it is uncommon for anyone to speak a second language. I know in Europe it is not uncommon to speak more than one language. I'm not sure about Australia. I'd try to do this as a poll, but too many variables. What I want to know is what country you're from, your primary language, and any second languages you speak.
