Left or Right Training

From our discussions this week referring especially to the left brain right brain discussions I ask the question of "Can someone be more extreme right brain or left brained if they were very dominate with either one noticeable more then the other?" But, since asking that question knowing that right brain is "artistic" and less "logical" then right brain folks.. What if someone trained themselves like some parents to their children when they're infants to become the handedness of their choice. But, the first question that came to my mind was is the brain to fully developed and wired to permanently to rewire it as an adult? Just think what if a left brained logical person could rewire themselves to accommodate their their job? Then as I was in my life issue's class on Thursday and we were talking about love, lust, and marriage the same question arose to me, what if someone could rewire themselves to match their mate's brain. Because if you think about it the divorce rate in America is 60%. What if the rewiring to become more like each other could save marriages, and give more children in America the wholesome family lifestyle, rather then a separated controversial one.
