Not
to
improve
your
backhand;
to
improve
your
brain.
When
reading
documents,
squeeze
the
ball
in
your
right
hand.
This
will
stimulate
the
left
side
of
your
brain,
the
side
that
processes
words.
If
it's
blue-prints
or
instructions
with
diagrams,
switch
to
your
left
hand.
Stimulating
the
brain's
right
side
helps
with
visualizing
and
spatial
relationships.
