My SWCAH son is a righty...But he is dyslexic, definitely a visual & hands-on learner. He struggled for years in school, until he was in 7th grade. Yes, lefties are right-brained. I once went to a dyslexia conference and was told that when a baby with dyslexic tendencies is exposed in-utero to high levels of male hormone, then the dyslexia is greatly magnified.
