In the not to distant future, as these neuroscientific discoveries penetrate deeper into the collective consciousness of humanity, hate, fear, violent behaviors or any untoward mental state or behaviors, will increasingly be seen as related to aberrant brain biochemistry, and eventually the current position that such mental suffering is a moral issue fade.  Dysfunction, addiction and violence will be increasingly understood to be predictable behavioral responses from individuals who suffer from sick brains, starved for proper nutrition, poisoned with neurotoxins and imbalanced by neurotransmitter abnormalities, all diagnosable with brain neuroimagery scans and laboratory bloodwork and other studies.  This is not to say that moral standards should not be expected and even enforced, but that the capacity for ethical choices in large part depends of the viability of the frontal lobes of the brain, and when the frontal lobes become increasing impaired by nutritional deficiencies, toxicities and neurotransmitter aberations, psychological dysfunction, addiction and violence become more likely. 
  When we can face directly the fact that the humanity’s hate and fear and its potential for violence and addiction are written into the fabric of our own brains, and that such potential is increasingly magnified by neurotoxicity, malnutrition and neurotransmitter imbalances, the whole perspective about ourselves and others shifts dramatically.  The geopolitical implications are staggering.  How do we solve that which is so deeply a part of our physical and psychological makeup? What are the implications of brain malnutrition and toxicity to tyranny, totalitarianism and terrorism?
  The medical and psychiatric consequences are also staggering and have barely been touched upon in healthcare.  The high pace, intellectual demands and complexities of modern life create an environment in which persistant stressors occur which can cause a chronic activation of the fight or flight response, making it hard for the body and brain to return to normal functioning.  Chronic activation of norepinephrine-driven fight or flight response leads to a wide array of medical and psychiatric conditions related to chronic stress, which may be the single most important factor in rapid aging, mental disorders and general human unhappiness.  Consider the list of symptoms and problems below.
