Your thoughts can cause pain.  When you have certain thoughts you will assume certain postures.

If you are depressed, you might hunch forward.  You get a depressed posture. If you don’t, you cannot stay depressed.

If you are sad, it’s reflected in your mouth and face and in your whole body.

When you are happy, it also shows all over.  You smile, your posture improves, you may even glow.  And your immune system will be happier, too!

If you continually keep thoughts that affect your body in a negative way, your body will get used to being in that position.  And when your muscles get ‘stuck’ in a position like that you will end up with pain.

Try this:  Change your posture.  Lift your shoulders and breastbone.  Change your expression.  Lift the corners of your mouth.  Let your eyes crinkle.  Smile.
