Simply put, RSI refers to the physical discomfort caused by our body's repeating certain actions. Imagine that, you sit in front of a computer for hours, keep your hands up flying over the keyboard and mouse, keep your eyes staring at the screen, ... so how can your body handle this? Over time, your fingers, wrists, elbows, shoulders, neck, spine will start to ache, twitch, pain, and become weak; especially your eyes will be sore, etc. These are warning signs from your body, so computer users do not neglect it.
