Try this in an elevator!
Stretch in a crowded elevator? You’ve got to be kidding. Give your eyes this special treat the next time you’ve got time to spare while going from here to there. Imagine a clock with images of your favorite foods replacing all the numbers. Keeping your head still, gaze up toward the number 12 position, (raspberries for me,) and hold for a moment. Next gaze down to the number 6 position and hold again. Then slowly move your eyes to the right to number 3, then to the left to 9. Complete the movement by looking softly straight ahead and taking a few deep, relaxing breaths.
