CORE QUESTION:
How old is old? Certainly, anybody over 70 might have a sufficiently
deteriorated brain that would keep them from learning as well as teenagers...
Neurons die continually, and with a few special experimental situations,
are not known to be replaced. On the other hand, the continued learning of
a lifetime builds new circuit connections and reinforces existing ones so
that the loss of neurons ca be offset by increased circuit capacity.
Cell death, per se, is not all bad - in fact it enables circuit creation,
which is most obvious in the young, developing brain where the greatest
amount of cell death, on a percentage basis, occurs.
OR HOW ABOUT THIS ANSWER?
every year, about 33,000 tons (30 million kilograms) of dust falls
into Earth's atmosphere and settles down to the surface of the planet.
The largest of these particles would just barely be visible without a
microscope, and most are far smaller.
Most of the dust comes from a belt called the zodiacal cloud, which is
formed by evaporation from comets, colliding asteroids, and a few other
sources. This diffuse band of dust is the cause of the "zodiacal
light," a faint glow of reflected sunlight that can sometimes be seen
just before dawn or after sunset, if the sky is very dark and clear.
CONCLUSION...
With age, as a person or the earth, the most likely learning problem is
with consolidating newly learned material. Previously learned material
typically persists and is often reinforced via rehearsal. This diffuse
band of dust is the cause of the "zodiacal
light," a faint glow of reflected sunlight.Neurons die continually, and
with a few special experimental situations, are not known to be replaced.

THANKS,
Now tell me how the DOW gets over 10,000 anticipating internet stocks and
gas prices rise a half a dollar in a month because summer in on the way?
