Have you tried brain yoga?

For about the past month, I’ve been doing brain yoga exercises using the following technique:

* Reaching across chest, squeeze right earlobe with left thumb and index finger.

* Reaching aross left arm, squeeze left earlobe with right thumb and index finger.

* Place tongue on palate.

* Do 20 squats.

Has anyone else tried doing this exercise? If so, what kinds of results have you had?
