Question: Does anyone know of any good sites for health and safety at  work while typing?

Answer: http://www.e-stretch.net/  provides Yoga stretch breaks especially designed for those who work at keyboards. There are stretches for the wrists and hands, the shoulders, arms and neck, the upper and lower body and the legs and feet. The stretches are timed and guided, so that no Yoga experience is necessary. Guidance is available by voice or text, and best of all, it’s free. Regular stretch breaks are the best known way to avoid RSI, and they can help relieve the symptoms BUT if you have pain already you should get medical advice IMMEDIATELY.
