What about people who learn more than one language at once in infancy? And I call BS on not being able to learn a new language once you're adult (that sounds like some american redneck mentality) I was raised on English and French (speak both with no foreign accent) and i've been learning spanish for almost 3 years now (I'm 27) and am now an intermediate speaker. I've traveled with it and have been able to have long discussions about alot of different things even though it wasn't perfect.
