I liked this video and suggestions. I certainly believe that genetics can be at play to a certain extent but that we can certainly influence genetic expressions for a positive outcome. I would submit that learned behaviours can be passed down through generations we can learn from our parents (and they from theirs and so on) such behaviours as expressiveness or inwardness. Regardless, though, as to whether genetics is responsible or socialization, I would agree that our patterns of behaviour such as the ones mentioned can be seen through our family line. I particularly appreciated the suggestion with respect to physical activity, i.e. one can have a catharsis [through sublimation we can redirect our anger (not exactly how it was phrased but I suspect Dr. Ahaddian uses a psychoanalytic approach at least in part)]. If more people heeded the advice about utilizing physical activity we’d certainly have a more active population which as we know is good for both mental and physical health. You can check out the video for more information. Tell me what you think about his perspective.
