This episode of Pneumatikos will explore the serious consequences of hostility to one's life.  "Hostile people release more adrenaline and norepinephrine into their blood than nonhostile people.  In general terms, these hormones raise blood pressure by constricting blood vesssels and increasing heart rate.  Angry people also have elevated cortisol levels...elevated cortisol levels cause the body to retain sodium (salt). which adds to the blood-pressure problem...over time if the hostility becomes engrained in the person's emotional identity, the blod pressure problems become more permanent."
