what I am saying is that culture is driving evolution instead of the environment. humans are evolving as to what the agrarian and industrial culture is deeming desirable. The latest growth in our cerebral area deals with these traits. For what ever reason if this latest developmental area is damaged or genetically suppressed you end up with the condition. It's not the condition that is so negative but the disorders that develop because of the social demands of modern life. Now, if we accept it as damage then we can proceed to correct the impairment by getting the brain to rewire itself with physical training.
