Yes. What divides the day-old and the million year-old organism in the battle against entropy?
Several orders of magnitude in time, but ultimately not much besides different strategies for temporarily delaying the inevitable. Complexity and regenerative abilities of the organism have something to do with determining duration. But basically, staying alive and complex takes more energy than dying and losing complexity, and lower energy always seems to win out in the end. There's a joke about thermodynamics with some truth to it about how you can't win, you can't break even, and you can't get out of the game. Plus, given sufficient complexity, things are bound to break down eventually in the stressful environments you get with living, and if you depend on all your systems functioning precisely to work, this can be something of a problem.
I still hold that there is more to death than the rearrangement of atoms. Among other reasons, a persons atoms are constantly rearranged without them dying, and a person can die without significant immediate rearrangement of atoms. That's not merely an emotionally charged view, I shouldn't think.
I would like to repeat my question to TurkeyOnRye as to how you define dying, given the statement "We are not dying. Our atoms are simply being rearranged." I'm interested in knowing what you mean by dying, if what we traditionally think of as dying is not?
