Well.... primarily because when a new life is formed, it is given genetics with telomeres of a predetermined length, consistent with the overall life expectancy of a naturally occurring organism and optimized for the time needed for that species to reach maturity and produce a strategically diverse selection of offspring. As cells replicate, the telomeres become shorter until the body's cells simply stop replacing themselves.<quoted text> No body loves hearing the word, death!
But every one must die, and science can not stop that, why ?
As the species intellectually progresses, more time is needed for reaching maturity. As the chemistry of the body becomes fine tuned, life expectancy can also be expected to be extended as the species is not expected to "experiment" as much with a diversity of environments.
Since humanity is now far less dependent on the natural vitality of the body and far more dependent on the intellectual abilities of the species to control medical science and the environment, it's natural to assume that life expectancy will dramatically increase in the near future.
The only real biological question is whether or not the species will find its niche in social stability or in constant conflict with itself. The simplest of truths is that death is fast becoming something that we actually do have a choice about, but the weight of the question is more about just how many years does one really want to have to explore one's own limited physical identity. At what point would altering one's physiology take away one's sense of "eternal soul" and reason for living?
Perhaps part of the cycle of life is accepting a death with dignity and to allow the one thing that makes life worth living, the unpredictability of the future.
Anyway, you're still a tired old bigot! English is not owned by England. Your literal views of the Bible are childish! Just saying!
