You know, there's a theory that if you know more than one language, it makes your brain stronger. That theory has shown up in scientific journals and newspapers and magazines.

The New York Times: The surge of emotion that makes memories of embarrassment, triumph and disappointment so vivid can also reach back in time, strengthening recall of seemingly mundane things that happened just beforehand and that, in retrospect, are relevant, a new study has found.
