Proper Breathing

prof daniel is complaining about my breathing through my mouth too much. suggested using yoga to teach proper breathing through the nose. will keep me from getting tired so fast. said one of his friends in norwalk teaching a special form of yoga for BJJ practicioners. he may do a seminar. he said even if i have to breathe through my mouth, i need to use my diaphram more. to let more air out and take more air in.
