[Paleopsych] The 25-Year Wait for Immortality

[Steve Hovland]

As with the current knowledge about longevity,
it's more about interest and effort than it is about
money.  Judging from the pictures I see in the
society articles, the rich aren't doing any better
than average in taking care of themselves.

But having the money and being willing to spend
it.  Right now if you want to consult one of the few
longevity doctors in the San Francisco area you
need to cough up $300 per hour out of pocket.
And it's not part of your HMO.

If there is a clash between mortals and immortals,
the immortals will tend to win because they will
have more life experience to bring to bear on the
conflict.

Someone has estimated that if you live 700 years,
you will almost certainly die of an accident.

A very old person would know that sacrificing
their life for an idea is something you can't do if
you intend to live for a long time.

Do you have any ideas or beliefs you'd be willing
to die for?  I don't.

Will the rich be the ones to benefit from this technology?
Will it be withheld from others? Patented?
Would there be a clash between mortals vs. immortals?
Should immortality be a universal right?
Will immortals ever risk their lives for anything?
Would life become too valuable to sacrifice for an idea?
