Super Longevity

Super Longevity

We should be able to live to 140 years of age. Middle age
might begin at 65, old age at 90. What is the clue to long life?
Surely it is keeping all your cells healthy so they can coordinate
the constant tasks of nourishing themselves, removing their
wastes, plus whatever job that cell was meant to do.
Since your cells divide and therefore start again at age zero,
even though you are 90, why do you age at all? Only the nervous
system does not divide. Is it the nerve that ages then, and decides
death for each of us?
It would never do to live forever. It would clutter the planet.
Are evolutionary forces at work preventing this? But we have
never cluttered the planet yet. So how could evolutionary forces
have “learned” to establish death to prevent overpopulation?
Living to age 140 is not living forever. Wisdom comes with age.
Wisdom would serve our society well. Perhaps wisdom is
needed more than ever for humans to survive. Part of the human
tragedy is war. Wisdom gathered from a knowledge of history,
might help end wars! But history can't be gathered and understood
in less than 100 years. If centenarians can't think well or
express themselves, their perspectives are lost. Longevity seems
a very useful trait if only it were accompanied by health!
