I wonder when one learns a second language has anything to do with some of this stuff. I have a feeling somebody that learns a second language later in life has a lot tougher time thinking in that second language without translating in their head than somebody that learns a second language as a young ***** or even along side their primary language their entire life.
I've heard a theory that people are all born with perfect pitch and they gradually lose it by the time they're 5. That explains the fact that people don't have accents in their ****** tongues, but do in languages learned after age 5.
