Anger is the fight in flight or fight, Sadness simply reminds of what is right, Love rewards us and tells our purpose bold, Empathy encourages, each has a story told.
Emotions are the most important thing, Does not matter if born a peasant or a king. We feel before act, moved deeply by the fact, That emotions are the key to life's abstract.
I think 200,000 years ago we reacted emotionally with much more intensity. Threats were real, your life could be lost in an instant with a predator or an adversary. We still have those very strong reactions which are built in to our survival design. But now we react with a road rage or an insult the way we used to react to a bear about to **** us. Emotions are fascinating. hh
