<p>Does anyone know what causes it and how to prevent it?</p>
<p>Its when you think faster than you can talk. You have to learn how to speak in exhales. Take an acting class, it really helped me!</p>
<p>Talk slowly; articulately. It makes you seem powerful and knowledgable. :D
Talking too fast will also bring upon you other things, which could be worse than stuttering...</p>
<p>Don't talk too slow or people will think you can't speak english! ;)</p>
<p>When you've had a little too much to drink you start stuttering, and slurring your words. Don't drink :)</p>
