Computer overuse. Conceptual computer artwork of a hand and a computer keyboard superimposed with clocks and the face of a distressed woman. This could represent constant computer use, internet addiction, or work-related stress. It may also represent repetitive strain injury (RSI), which may be caused by prolonged and repetitive movements, such as typing. Problems with the joints of the fingers and wrist, including tendinitis and carpal tunnel syndrome, can be exacerbated by prolonged keyboard use.
