Posture up for health and confidence

What is good posture?  When you have good posture you allow for equal distribution of weight of your head onto multiple muscle groups and joints.  To obtain good posture elongate the back of your neck, tuck your chin in comfortably and pull your shoulder blades down.  This will put your upper head, neck and upper body in a better position.  As your chin drops forward when you are on the computer use these cues to get you back.

Posture also effects how you feel.  See the following link from a Ted Talk that will tell you how.
