So I am a really fast typist. Sometimes so fast, that I start to type the next word I'm thinking of before I've finished the last. I tend to do things really well with hand-eye coordination like typing, Tetris, playing the piano, anything along those lines. Sometimes at night before I go to sleep I play tetris in my head or imagine a big keyboard and type what I'm thinking. Yes, I am a very complex creature. The thing is, I really enjoy typing, but I hate sitting at a desk all day, I need some type of system to where I have to walk on a treadmill to make my keyboard work haha.
As much as I appreciate grammar and enjoy typing, there are a few words I can never get right: "guarantee", "confirmation" always comes out "confirmatino", I can't ever get "with" to not come out "withe".
But everyone should do this when they have some spare time (if your a big time left-brained weirdo like me)
Let me know your results :)
