Carpal tunnel syndrome

I just learned that typing too fast or too often can give somebody Carpal Tunnel Syndrome, or some physical disorder wherein wrists nerves becomes too compressed and unable to perform, which leads to hand numbness and weakness. I believe I have been typing too much lately so I'm gonna take a little rest from those typing exercises that requires me to write a 20-page short story in less than thirty minutes. I don't want my precious wrists to suddenly fail and make me a victim of another work related disease. I already have myopia, in case you didn't know.
