Acupuncture, what we do is, we insert very tiny needles in different areas, acupuncture points. We look at the meridians. And when we talk about the meridians, I give the analogy of the blood vessels in our body. We have blood flowing throughout our body. Same thing with the meridians, except it's energy flowing through these meridians. There are certain times that, for one reason or the other, energy gets stuck. And so, we use acupuncture as a way to keep the chi, which is the energy flowing, so to promote better health.
