Another brain gym exercise found in the Dennisons' book, Brain Gym, is called the Balance Button.  It helps with thinking, relaxing for test taking, and organizational skills.  While sitting down, touch two fingers to the indentation at the base of the skull, behind the ear.  Rest the other hand on your navel.  Imagine breathing the energy up through the body, slowly and deeply.  After a minute, switch hands and hold your two fingers behind the other ear.
