@Leadfoot,
one of the 10 foundations of life on the planet include apoptosis at cellular and organ levels. Does this translate to a predetermined max life span??
Why or Why not?
We cannot control the weather or seismicity and the approach of Andromeda, but we can understand the mechanisms so why are we making some big "religious mystery " of the termination of an organisms life.
As Tithonus was granted "eternal life" by Zeus, somebody forgot to include a conferral of "eternal youth" on him so he just wizened away forever, watching everyone else blossom in their fullness and go along till death came along , all in its time.
Positional nodes (like telomeres on a chromosomal gene)include the "transmitting of" Enzymatic "cascades" which have a habit of increasing geometrically during the existence of an organism and although" physiological degenerative diseases" can be whipped, as seen in mice studies, the result is an increase of cancers one of the biggest determining factors of cancer susceptibility is age . We should all read about "
gerontogenes and Weissman's erroneous conclusions that death in an organism iw "preprogrammed"
Interesting subject, much studied, few conclusions, but its no real mystery
