A Kingtrumpet, Mr. college grad... Perhaps a review of the English language is in order at this point: flush 1 (flsh) v. flushed, flush•ing, flush•es v.intr. 1. To turn red, as from fever, embarrassment, or strong emotion; blush. 2. To glow, especially with a reddish color: The sky flushed pink at dawn. So this just about negates all the advice from your post above. If you get in the right amount of air, we go in this direction, Oh hypoxic one!
