Can your keyboard kill you?

Repetitive Strain Injury (RSI) could be caused by radiation emitted from keyboards. No, we're not making this up.

A letter published in the December edition of Journalist, the magazine of the National Union of Journalists (NUJ), speculates whether the "electromagnetic radiation immediately under each fingertip" could be to blame for the debilitating and painful condition.

The letter reads: Has anyone explored the possibility of RSI being caused by the radiation emitted by keyboard strokes every time one keys a letter? The make-and-break of electronic keys must issue a short burst of electromagnetic radiation immediately under each fingertip and the body's nervous system comprises a myriad of electrical pathways - might it not have a cumulative adverse effect?
