Sit up straight!, Don't slouch!, admonishing words that many of us have heard from our mother's during our childhood. If you were smart enough to not have ignored them you probably realize it today in your adulthood that mother always knows best because good posture is important. Its important because 1) it sends a message about how you feel about yourself, and 2) good posture can make you appear taller, thinner and more at ease. So what exactly is good posture, lets try to understand this a little more. Think of your body as a building, an architectural marvel designed to work with the force of gravity such that no one structure is over-stressed. In the physical world an architect has to take these same laws of gravity and weight distribution into account when he or she designs a building. And like a building with a poor foundation a body with poor posture is less resistant to the strains and stresses we experience over the months, years and decades of life.
