I can think of one reason, how true it is I don't know because I've
never actually tested it out with a static meter.

When your shoes (especially nike's or reebok's) rub against the ground
(or even better a rug), they build up a charge. This is called a
triboelectric effect. Most people realize this by the ZAP they get
from a door knob or equiv. What most people don't realize is that
there is also an electric field associated with this charge and *that*
is probably the reason why it's been suggested to move your tower.
Like I said I don't know how true this is. I use a tower in the lab
and me reebok's are right against it. I haven't lost any data yet.

 Hope that helps,
mike
