You should take a typing class if your school offers one and you plan on remaining such a huge nerd. Your wrists will thank you when you're 80.
I can type 116 words a minute for hours at a time and my wrists never hurt ever. I had a great typing class in high school that turned me into a robot.
The only time I ever hurt my wrists is when I have a couple finals in a row and I write essays with a pen for hours at a time. Or when I try some dumb breakdancing move.
