Um, forces don't propagate instantly. They propagate at the speed of
light, because they arise from the exchange of momentum carried by
virtual photons. This is demonstrated as part of Richard Feynman's
theory of Quantum ElectroDynamics (QED - for which he won the Nobel
prize in 1965 - see here for his wonderful Nobel acceptance lecture:
http://nobelprize.org/nobel_prizes/physics/laureates/1965/feynman-lecture.html).
The same applies to information. The speed of light sets the upper
limit on the speed of propagation of information, because information
requires the exchange of energy, therefore photons.

So the fastest that information about the status of any individual
neuron could possibly propagate to the center of mass would be exactly
299,792,458 m/s, and that would only be true in a vacuum. If there is
actually any substance inside one's head, then it would be
considerably slower.

Also, there is a well-known relationship between mass, gravity and
acceleration (this is the subject of Einstein's Special and General
Theories of Relativity, STR & GTR - but apparently neither of those
were worthy of the Nobel Prize). The faster one is traveling, the
heavier one gets. Therefore, if one moves around a lot, any mass
inside one's head gets more massive, which will slow down the
propagation of information even more.

>From these considerations, we can draw several conclusions:

1) People with empty heads will process information more efficiently
because there isn't anything in there to slow down the speed of light
from its vacuum limit.

2) People who do not have empty heads should move around as little as
possible, so as to maximize their information processing speed. This
is precisely why the wisest people (e.g., Buddha, Newton) spend most
of their time sitting peacefully in one place and meditating.

3) Because gravity also makes things more massive (i.e., it is
functionally equivalent to acceleration, according to Relativity
theory), the most efficient information processing would be achieved
by sitting perfectly still, far out in space away from the
gravitational acceleration produced by nearby massive bodies like the
earth. This is why so many stoners think such deep thoughts. But they
have a hard time communicating their insights to people (on earth),
because such communication involves motion, which itself interferes
with the deep thoughts.

4) Finally, I do not know exactly where the center of mass of my own
brain is (though I strongly suspect it is about a foot to the left,
about six inches above, and about eight inches behind the center of my
skull - at least that's where the inner voices I hear seem to be
coming from). I do know, however, that it is the place where I think
my weightiest thoughts.
