I like Rowuk's explanation of the breathing cycle; here is a down and dirty breathing trick: THE VULGANO TIOLET PAPER ROLL TRICK Take a used cardboard toilet roll and stick it in your mouth (this is the "dirty" part of "down and dirty," and any type of tube will do, actually) and breathe in as fast as you can. WHAM!, the air comes rushing in. Why? The back of our tongue drops with the tube in, and opens things up. Memorize the feeling, sound and everything and start appying it to your breathing without the tube.
