I just have the feeling that certain people in this thread feel they cannot be wrong because they have a ton of 'evidence' to back themselves up.

Anyone learns anything from a young age will become proficient in it(be it mathematics, music, art and etc). Remember the 10, 000 hour rule? The more you do it, the better you get at it.
