On Betting on Aging
By Douglas J. Wagenaar Ph.D.
Aging and limited life spans1 are nature's way of ensuring steady
rates of mutation and varied DNA
combinations in order for life forms to advance through evolution. If
life forms did not die, there
would be less of an opportunity for favorable mutations to
promulgate. This has worked pretty well up
until now. A few decades ago there was concern that advances in
medical science to extend the life
spans of people with weaknesses or disease susceptibility was
"anti-evolutionary," that survival of
the weak is not natural. This is now an invalid concern, and what has
changed in recent years is that
the entire evolutionary, natural model is now obsolete, given our
ongoing understanding of the
genome. Breaking the genetic code allows us to perform genetic
engineering, computer modeling of
DNA combinations, create new life codes such as peptide nucleic acids
(PNAs), and other "unnatural"
but rational, directed kinds of advances to new life forms that do
not have to abide by the
established rules of natural selection through eons of slow mutative
On the limit of human life spans, my opinion is that within the next
150 years someone will unravel
what constitutes human consciousnesses and memory--the real essence
of what it means to have
human life. If we can store consciousness and memory on a computer
disk (or its equivalent), the life
spans of humans will be immediately extended beyond centuries, and
human life will become equivalent
to the machines (computers) we have used to model DNA and to decode
the essence of
consciousness and thought. (These comments are my personal opinion
and are not intended to
represent the views of Siemens Medical Systems.)
