I’ve been using Les Fehmi’s Open Focus Attention brain exercises for awhile. They work. How? By doing simple exercises that focus on your body’s relationship to space, you change the way you pay attention, and that changes your brain wave activity … which changes your physiology and the hormones and chemicals that keep our bodies going. Of course, sometimes the hormones and chemicals run amock and flood our system with emergency chemicals that we don’t need, as if we’re in a constant state of “fight or flight” emergency mode. By learning how to manage your attention and how to develop “attentional flexibility”, you can find relief from stress, anxiety, and pain
