Tai Chi teacher says stand straight and we think we are. Then you have someone like Susan Matthews adjust your posture to be straighter and you feel kiltered to one side or another. We think we’re straight and we’re not. Becoming sensitive enough to recognize the difference between straight and not straight is a core objective of tai chi. The more precisely we’re aligned the more efficient we are in movement and the less wear and tear on the body, and more efficient our brains will function, because we have more energy available to us to do the real reason for living….enjoying life!
