The Hunchback of Notre Dame with a computer

Do you remember the movie The Hunchback of Notre Dame? Quasimodo? Well I'll be honest, I just remember a guy being hunched over and that's about it. How does this correlate to computers?  In the recently months, my posture has been brought up to my attention. I hunch over when I am at a computer and in the long run, this really could affect my back. I tend to spend many hours at the computer coding away. I took action right away and bought a TKO Anti Burst Fitness Ball. How does this ball help? This allows me to focus my attention on my back by stabilizing and keeping it straight. Based on my week of use, I can say that I have noticed that my back and core have been sore. I have forced my body to stay up straight and stabilize itself.  Remember, I not a chiropractor.
