Tongue and cheek, tongue in cheek, which is it?

I went to the qigong gathering early this morning about 7am. Dark as usual and we are not quite into the daylight savings time. Yet for those over 60, what is daylight savings time anyway? But in anycase, we were doing the tongue in cheek exercise. What’s that?

Funny you should ask. It is a simple exercise where you push your tongue into your cheek, say starting from the left side, then you continue pushing it [your tongue] over to the top of your mouth, going around to the right side, down and back to the left. While doing this in a clockwise circle, about 5 or 6 times, you are standing with your feet flat down on the ground, and you rise onto your toes. Meanwhile you press your hands to your intestine.

Interesting process, so what will it do for you besides make you look funny to others as you ride the subway? This process will stimulate your salivation glands and put the juices in your mouth, which then will flow down to your stomach to help make more acid for you to digest your food.

Well, if you don’t believe this, then you need to take all this in “tongue and cheek.”
