The face and eyes of police and first responders provide a window into the internal world of thoughts and feelings. When exposed to danger, adversity or traumatic events, they learn to cope, over time, by presenting a mask of calmness, strength, and resiliency. Below the surface lies the accumulating stress, adversity, and trauma whose very presence is harmful to the mind and body of the individual, a lurking danger whose existence may lead to severe consequences.
