Aging

The process of becoming older, a process that
... is genetically determined and
environmentally modulated. Research into aging: To sum up the state of research into
aging is well beyond the
confines of this space (and this
writer's talents).

However,
here is one type of research
into the genetics of aging. A gene has been discovered that helps determine the life-
span of the fruit fly
Drosophila. When the gene is
mutated (altered), it can
extend the life-span of fruit
flies.
It doubles their life-span. The gene has been named
Indy (for I'm not dead yet). It
appears that the protein encoded by this gene
transports and recycles
metabolic byproducts. Defects
in the gene may lead to
production of a protein that
renders metabolism less efficient so that its body
functions as if the fruit fly
were dieting, even though its
eating habits are unchanged.

Mutations in Indy thus appear
to create a metabolic state that mimics caloric restriction,
which has been shown to
extend life-span.


Some useful suggestions for extending life: No known substance can halt aging or
extend life, but here are some
useful tips for improving the
chances of living a long time
and staying healthy:

1. Eat a balanced diet,
including five helpings
of fruits and
vegetables a day.

2. Exercise regularly
(check with a doctor
before starting an
exercise program).

3. Get regular health
check-ups.

4. Don't smoke (it's never
too late to quit).

5. Practice safety habits
at home to prevent
falls and fractures.

6. Always wear your
seatbelt in a car.

7. Stay in contact with
family and friends.

8. Stay active through
work, play, and
community.

9. Avoid overexposure
to the sun and the cold.

10. If you drink,
moderation is the key.

11. When you drink, let
someone else drive.

12. Keep personal and
financial records in
order to simplify
budgeting and
investing.

13. Plan long-term housing
and money needs.

14. Keep a positive
attitude toward life.

15. Do things that make
you happy.
