What's the connection between a thought of regret, or of resignation to a negative situation, that causes humans to involuntarily fill their lungs and exhale slowly? Is such sighing learned behavior? Does every culture sigh for this reason? Animals sigh. When my dog sighs, is she laying there regretting she didn't roll in that dead skunk when she had the chance?
