Ear nervous system exercise:

Hitting the ear drum.

Cover your ears with your palms, fingers pointing toward the back of your head. In this position, flick your index fingers against your third fin­gers so that the index fingers drum on the lower edge, or occipital bone of the skull. This will sound quite loud. The flicking of the finger that hits the bones will vibrate and stimulate the nervous system, the ears and the inner ears’ mechanism. Repeat nine or more times. (Fig. 4.34) The activity of the ear will be balanced and the mastoid sinus improved by this exercise.
