Mouth

Yes the mouth, just notice how it expresses your feelings.

If you instruct your mouth to smile then notice how your mood lightens.

Do not take your mouth for granted.


Exercise it for more than eating, talking,singing and so on.

Smile.

Why?

Because if you do not then over time your mouth tightens, and voila you have a mean mouth.

No one wants a mean mouth.

Be nice to your mouth.
