As we grow and our lives unfold, our body records important information.  

We don't need to learn how to do things twice. Once we learn it, the body remembers how to do it - like riding a bicycle. The channel of energy that recalls and remembers the activities throughout our life is called the Yang Linking channel or Yang Wei Mai in Chinese. 

If a movement is associated with a traumatic event - you might not be able to stop doing that action, until this channel is treated.
