The damage many Americans have goes a little further than that

interesting wonder if there will be any dye-trace studies done i love those.
frontal lobes are different to the "ventromedial prefrontal cortex" though frontal lobe damage usually results in personality change and makes people more aggressive, (its not documented whether they fail comprehension of sarcasm or not though!)
i know that because i revised it last week. dont hurt me
