You might find this interesting, even if you don’t agree.
It's an interesting insight of some of the ancients to say that. Modern science confirms that a living cell is not programmed to die, but rather to live indefinitely!
Rather then being rooted in sin (although an argument can be made that sinful ways contribute heavily), natural "corruption" (aging and death) of a cell is brought about by accumulated damage from the cell's own metabolismfree radicals, released from the cell's mitochondria (metabolic power houses), that relentlessly bombard and damage our DNA.
The body constantly repairs this damage (that's why you need 8 hours of sleep), but it's a losing battle over time. Natural aging and death is simply a sum-total of damage and repair done to our system, "wear and tear" if you will, as the body's own ability to repair itself is overwhelmed by the sheer magnitude of damage incurred over time.
So, while the body was not created to die, it dies from its own wear and tear, from its internal combustion byproducts; ironically, the cell dies from its very essence of lifeit burns faster than it can build.
Studies have shown that different animals of approximately the same size with different average life spans invariably show that those species with lower free radical production live longer and age slower.
We could argue that sinful lifestyles tend to increase body's "wear and tear" and minimize body's self-reparing mechanism (lack of sleep, excesisve exposure to sun), etc., in addition to our genetic makeup, but the fact is that even saints dienot so much because of Adam's transgression but because their cells produce highly reactive free radicals.
