On Thursday Barack Obama awarded Joe Biden "The Presidential Medal of Freedom". Vice President Biden is one of the few who have also been bestowed with the additional honor "With Distinction".
From a nonverbal perspective, Joe Biden displayed "The Puffer Fish" at multiple times during the ceremony. The puffer fish is a characteristic out-pouching of the cheeks with slow exhalation (although it may occur through consecutive breathing cycles).
The Puffer Fish has the benefit of lowing the blood pressure and the heart rate. It's also consistent with deeper breathing at a slower rate compared to baseline. The net effect of The Puffer fish is to have an overall psychological and physiological calming effect.
Take care to avoid confusing the puffer fish display with "Tight Lipped Breathing" which can look somewhat similar but has a completely different meaning and effect.
