Do you ever stop and think about death?

I have been thinking about that moment between life and death. That split second between possibility and infinity. One moment, there is life, a heart beat, breath, thought, animation. All the chemical responses and electrical impulses that go to make up a living, breathing creature.

Then, suddenly, between one heart beat and the next, that all stops. Life is irrevocable. Gone. Ended. You can't grab it back. You can't pull someone back from the brink.

Where does the energy go? Physicists have us believe that no energy can be destroyed. Is that the part we call the soul?

How can someone murder someone else? How can they bring themselves to extinguish that fragility?
