Why move the Qi in our bodies?

Why do we want to move the Qi in our bodies?
Illness occurs when blockages build up; clearing the meridians to allow the free flow of Qi is necessary for the restoration of health. Qi Gong helps to clear the channels, thereby making the restoration and maintenance of health possible. According to Traditional Chinese Medicine, there are channels in the body through which Qi (Chinese word for the vital force energy in our bodies) flows; a person is healthy when the Qi is able to move freely along these channels (“meridians”).
