I have been told (don't understand it though) that crossing say your right hand to left foot makes some change in your energy channels. When I am walking and tired or my l-dopa is low and I need to take some...my left arm may stop swinging and even come up and look like a puppy begging in front of me. If I take hold of my left hand by the wrist with my other hand and stretch it as far as it can go out past my right shoulder, it will go down by my side and begin to swing normally again..at least for a while (til I take my fava tops tincture and get jumpstarted again
