Where heroes come from.

September 11th, 2001 was just another day in the beginning.  All over the country people got up and went to work, life went on as usual.  That it was to be the last day for countless heroes, was beyond their knowing.  These men and women, mostly firefighters, first responders, and cops responded to a distress call like they had as part of their jobs each day.  This distress call was however, unlike any that came before.  They didn't know it at the time, but America was at war.  They were asked to respond to a cowardly act of war that cannot be compared with the Day of Infamy witnessed by the Greatest Generation.  Pearl Harbor was an undeclared act of war by a nation against another.  Armed forces fought each other that day, and those who lost their lives in the Arizona or elsewhere died in the service of their country.  9/11 was an act of terrorism against unarmed non-combatant men, women, and children.  It was no better than walking into a pizzeria and blowing yourself up.  Moral outrage is meaningless to those who don't value human life.
Such was the situation that these public servants rushed to confront as they converged on the burning towers.  Most did not return.  They left behind wifes, family, children; but they brought out of the fires thousands who would live to hug their own families because of their sacrifice.  They didn't know when they put on the uniform to start another work day that the ultimate sacrifice would be asked of them.  Were they scared?  Sure.  Hesistant?  Perhaps.  We honor them today because they went forward anyway.
Ten years have passed.  Wars have been fought in retaliation.  Thousands of soldiers have joined these men and women in sacrifice, and tens of thousands have returned home wounded in body and spirit.  Time will heal all wounds.  Decades from now few will be left who remember that day, as a new generation grows to adulthood in the shadow of the freedom provided by those who know that it is not free.
So where do heroes come from?  Most don't make a choice ahead of time to be a hero.  Heroes choose to put others ahead of themselves each day through small acts of service and sacrifice.  By dedicating themselves to help those in need they have already made the choice to trade their own lives for those of others.  All the men and women who put on uniforms that day (and any day) were heroes, some were asked to pay for that honor one last time.
