In your opinion, "What is a Hero?"

Heroes possess and demonstrate courage at least for the time they are being heroic. Courage occurs in all walks of life and has occurred in all epochs since people began communicating on cave walls and animal skins.
Heroes are not glory seekers and they are not foolhardy. Heroes rise up when needed, do what is required and recover afterwards frequently avoiding the limelight.
Being courageous requires overcoming a level of fear and overtly or tacitly accepting risk on the behalf of others. Heroes are all around us - in addition to those who protect and defend us in the police, fire departments, military members, security services, medical and trauma personnel, teachers, children in the schoolyard and neighborhoods standing up to bullies, drugs, gangs; people who donate kidneys and other tissue which can be used to save somebody else's life.

I've seen this discussion a couple different times....so here is a totally different answer for a new thread.

A hero is a victim of circumstance. In that moment, he longs to be an honest coward.

You'll see him when things are at their worst. When things are at their worst, he'll tell you everything will be ok. When things are ok, he'll be gone.
