A fixed habit is supported by old, well-worn pathways in the brain. When you make conscious choices to change a habit, you create new pathways. At the same time, you strengthen the decision-making function of the cerebral cortex while diminishing the grip of the lower, instinctual brain. So without judging your habit, whether it feels like a good one or a bad one, take time to break the routine, automatic response that habit imposes.
Deepak ChopraYou can free yourself from aging by reinterpreting your body and by grasping the link between belief and biology.
