Query: This video saved my life

I bought this video almost ten years ago and it has seriously changed my life. I was diagnosed with carpal tunnel and arthritis around that time and they suggested surgery, today I am surgery free. Anytime i feel pain, I do this video and it is like magic. It has helped me with everything from sore hands to constipation to a sore neck. I love it and would recommend to anyone!
