Another good thing about bilingualism

A meta-analysis of brain studies suggests people who speak two languages have brain differences from monolinguals that give them an advantage in mastering other complex thought processes, including "learning in general, complex thinking and creativity, mental flexibility, interpersonal and communication skills, and even a possible delay in the onset of age-related mental diminishment later in life." They highlight improved short-term memory.

And they say it is dose related: It starts when you start learning a second language and gets better as you get better at the language. But learning a language as a separate school course doesn't work as well.
