I read somewhere that it's something we end up doing subconsciously most of the time to eliminate utilizing the part of our brain that deals with speech from the thought process. so that we can devote all of our thoughts to the task at hand. Interesting right. I've been doing this ever since I can remember, and I never notice it at first.
