	Stages of Yawning
		Can you tell: (1) Initiation, (2) Acme, (3) Conclusion
			
            
            
            
			Look for (1) Initiation: opening the mouth widely
			  (2) Acme: thorax reaches maximum capacity, 
			      breathing stops, eyes close, Pandiculation
			  (3) Conclusion: short expiration
