"Setting up your computer may seem as easy as pulling up a chair and reaching for the keyboard. Yet positioning or using your computer improperly can lead to all sorts of injuries - from the short term discomfort of headaches to long term (and potentially debilitating) conditions like Carpal Tunnel Syndrome. Many people don't even realize that their pain is computer-related - until they learn proper work habits, and the pain disappears."
