What is RSI?

Of late I have been experiencing some pain in my wrists due to the way I type on my laptop. I have heard of this term called "Repetitive Stress Injury". Thought I should check out some information on the net about this and found this blog entry. Found it quite informative. Do have a look: Link to Scott Adams' blog (not the Dilbert Scott Adams, I presume). There's quite a lot of info on RSI and how we could avoid it. Google it and you'll find out.
