I lasted about 19 years.
Couldn't have held out for an even 20 from the year 2000.
Too much Evil.
The images under the Tribute section of FranZetta's work honoring the children who were murdered profoundly affect me even to this very moment. If you have not known loss, if you have not experienced State-Sanctioned Murder, then you might not be able to plumb the Depths of Hell. That's OK, we'll take you there, you can look over the Edge safely, we will not push you, but if you decide to jump on your own accord, just realize that there is no bottom.
“Beware that, when fighting monsters, you yourself do not become a monster... for when you gaze long into the abyss. The Abyss gazes also into you.”
― Friedrich W. Nietzsche
