>sighs could signal a behavioral state change [...] Teigen (2008) also describes situations in which sighs are elicited by a quick drop in physiological arousal, during situations in which humans feel helpless and surrender. The source is my source. What really gets my goat is the Goldilocks findings; too little sighing and baby death occurs, too much and adult depression sets in. It's all too convenient a match for the present moral zeitgeist of the expert external savior. The study ignores ways anguish can be prevented (in adults) because it doesn't dare find fault with any actors in a situation, instead it looks to play the defeatist mindset off as natural & necessary from earliest life.
