The correspondence between early embryonic cells and
tumor cells has fascinated researchers for many years.
A great deal has been learned about the death of cells by
studying cells that have somehow evaded it. And it is
inescapably true that the death of human being begins with,
and is ultimately entirely explainable by, the death of
individual cells.

The two deaths cannot be separated from one another; they
are the same death, whether we write on hospital chart that
death came from a "heart attack" or "cancer" or simply "old
age." Yet as we have seen death is not, a priori, a
requirement of life. Somatic cells --- and thus the need
for compulsory somatic cell death --- arose only after DNA
began making copies of itself that would be used for
purposes other than reproduction. For humans this means
that once a reasonable number of our germ cells have been
given a chance to impart their reproductive DNA to the next
generation, the rest of us --- our somatic selves ---
becomes so much excess baggage. That is the biological
origin of senescence and death.

From a human point of view, it is our somatic selves ---
embedded in which are things like mind, personality, love,
will --- that we cherish most and that define us, to
ourselves and to others. We think of reproduction as only
one of many activities we can choose to engage in. Perhaps
this is not surprising, since it is a point of view arising
in the somatic part of ourselves --- in our minds. We have
used our minds to invent complex belief systems to explain
death. None of these paint a picture of ourselves as excess
baggage; none cast us simply as tools for transmitting DNA.
Yet when we trace the origin of our death beyond mind and
belief, to its true beginnings --- the death of individual
cells -- we come to a rather harsh and unflattering
conclusion: the irrelevance, in the grander scheme of the
universe, of our somatic selves. No wonder belief so often
triumphs over reason.

Pg 103-104 Chapter 4:From Sex to Death
Sex & the Origins of Death by William R. Clark

I got this book in 1999 as some reading about life and death when I spent the spring helping my sister care for her hubby who was dying of cancer. Just got around reading it. Did read or was read to many parts of the Bible during that time, it was about hope and fear and no time to reason.

Still haven't finished Zen and The Brain by Austin --- read 200 pages of 870--- it was the cats that bugged me.
maybe I'll look at it again.

"programmed" death results on a cellular scale

You are probably referring to the telomere part at the end of DNA strands, which half every time DNA reproduces. A point comes when it is so short it cannot half anymore and hence the cell can no longer reproduce.

In experiments, lab rats with stimulated telomerase production (can't remember the exact method) lived twice the life span of ordinary rats...
