Marcus Luttrell, the former U.S. Navy SEAL upon which the upcoming movie "Lone Survivor" is based (starring Mark Wahlberg and to be released next month and based on the nonfiction book of the same name by Luttrell) is shown here in this heart-wrenching "60 Minutes" interview.
He did this just after he said, "[deep nasal inhalation]... You know they, they, they say every man has his breaking point. I never thought I'd find mine. The only way you break a Navy SEAL is you have to kill us. But I broke right there. I quit right there. Ahhhh ..." acknowledging his momentary inaction as his friend lay dying. The lone survivor's lip biting is indicative of anxiety and emotional suppression of sadness as well as helping to prevent the expression of tears.
Lip biting can indicate other emotions depending on the other nonverbal signals with which it is clustered.
Note that Luttrell looks down and to his right at this same time. Gaze in this quadrant is highly correlative to highly (usually negative) emotional tones - particularly in right-handed individuals.
