A few comments...
There are two movies called Jacob's Ladder.
The one I saw was about a dieing Vietnam soldier who had been exposed to
a nerve agent called BZ which presumably causes Paranoia and Psychedelic Hallucinations,
and he was in a coma, experiencing a terrifying unreal nightmare.
My own perceptions of the potentiality of extreme longevity predate many sci-fi and
scientific ideas about how to achieve it. For example, potentially buggy technologies
just as autonomous and possibly self-replicating nanotechnologies are "yucky" to me,
and I don't have any desire to be "assimilated by the Borg", I don't believe in uploading
my self into a computer, etc.
There is a debatably short but undeniably straight line to indefinite life extension.
In other words, life extension is both the process and the goal itself. In other words,
If I had exactly what I was looking for, I could start extending my life immediately.
Methods like the ones in the previous paragraph seem to me like concepts of
constructing a HUGE life support system, or like holding together what's falling
apart with a truckload of duckt tape. But I am a minimalist, able to do incredible
things (make advanced technologies) with fewer parts than people assume are
necessary.
I am focused on the elements that affect lifespan.
That sentence has multiple relevant meanings to me, most of which I am sure
will be overlooked. The ideas are simple but obscure because the thoughts
are not common. For example, it should be obvious that the fountain of youth
provides water. In considering the fountain of youth as a credible candidate
for life extension (AS AN EXAMPLE) you may need to suspend disbelief to even
notice that it provides water. Or has anyone wondered what could cause
water to extend life before now? The idea of the fountain of youth may have
originated in REVELATION 21 and 22, if not earlier. Since Methuselah died 969
years old on the day of Noah's flood, there is an implication that the flood water
is somehow different than the water that Methuselah drank. And this would be
the reason for looking for life-extending properties in water. Also, where did
the flood water come from? The sky? If so, then the AIR has more or less water
than it used to have. If the earth had no oceans, maybe the air and water were
mixed together before the flood. So it is interesting to ponder what kind of air
Methuselah breathed also. That is a reason to look for life-extending properties
in air. And so forth...
Test all simple possible causes of failing to outlive Methuselah. How are we different?
One must first accept the possibility of indefinite lifespan to be able to seek it.
