Dr. Andrew Weil, M.D. (famous author, Harvard physician and natural healing advocate) says that we have to be careful of our posture. So, when you are walking, keep mindful of that! He calls the old technique of book on the head “finishing school”, but suggests Alexander classes, as well as the Feldenkrais and Trager approaches. These are various motion classes and alignment techniques. All kinds of ailments can be fixed with correct posture, so keep that in mind when walking!
