Definition of Death -

Situation wherein something or someone that was once a living breathing being, no longer breathes or has any bodily function whatsoever. The heart stops, the brain stops, the blood turns cold and the body begins to decompose.

What happened to the life force that was making this body live and breathe and where did it go?

What is the life force?

Energy cannot be created nor destroyed, so where did the energy go?

Any thoughts on that?
