I blame this on the fact that I have to glance at my keyboard every few words, due to the fact that I learned to type while playing Counter Strike at the age of 9, and would look at the keyboard every time I started to type something. When I'm writing off of the top of my head I can easily type at closer to 100 WPM since I don't need to look up.
