It happens, when it happens, for the first hour or so and for the first few days. When
using your old mouse the body’s only defense mechanism against low circulation was to
release a type of hormone, a vaso-dilator, to increase the size of your blood vessels to try
to let more blood through. The release of these hormones becomes autom

days for the body to realize this is no longer necessary. During that time more blood than
is needed gets to your hands and so they get hot.

These muscles are bigger and better equipped to do this sort of w

and backwards it moves blood to and from your fingertips (this is why the arms are
pumped arms when running).
7. Mousing Accuracy
This will not be a problem for standard tool bar icons, though some conscious thought
might be needed in the first few days and the explanation that follows applies to those
who do more accurate pointing work also. Conscious effort in pointing with upper arm

the process itself and you just think right turn. Then the lower part of the brain, that now
knows what a right turn means in terms of muscle movement, takes over, leaving the
conscious brain to think of something else. It is the same with mousing.
