Fellow speaker,
Professional speaker Patricia Fripp suggests warming up your eyes by looking at an imaginary huge clock, look on the imaginary face of the clock at the 12 (eyes up), the 3 (eyes right), the 6 (eyes down), the 9 (eyes left), and and then the 12 (eyes up) again. Repeat three times. Then reverse the direction of looking (i.e., look at the 12, the 9, the 6, and the 3) and repeat three times.
Clocked,
Tim
