• Experiencing any kind of emotions encourages people to share

• Talking to others often make emotional experience better

• Sharing emotions helps us connect ( it highlights similarities and how much we have in common)

Science of physiological arousal

• Emotions should be classified on activatoin or physiological arousal, instead of possitive or negative

• when aroused, we do things.

• anger, awe, anxiety and etc. are high-arousal. 

• Other emotions (sadness, contentment, etc.)have opposite effect: stifle actions

physical arousing also lead to same result
