pain is the voice of the body when something is wrong. have taken mine in today for the whirling noise. you should not go in without understanding it, and you want to understand what to expect. i do like sliding around on things: skis, mountain boards, skates, with wheels and with blades. a wine cellar with room for 2,000 bottles. but what i do care about is gathering together and sharing a meal with your family on christmas day. if you take the time for a daily meditation practice, your decision-making process will be much more controlled, focused and clear.
