If you are interested in what grounding can do for your health, you should watch this Youtube video. As for me: after having experienced how my being actually left my body and sank through the bottom of my parked car, and into the Earth, I came back up with a constant feeling of energy flowing through the soles of my feet, whether I walk barefoot or with shoes. Actually, I need shoes sometimes to lessen the feeling of the flow, as it becomes uncomfortable.
