Stories are powerful. Evolution has wired our brains for storytelling. We all love a great story.
For over 27,000 years, since the first cave paintings were discovered, telling stories has been one of our most fundamental communication methods (Source). Stories help us connect with each other and are an important part of our existence. We feel more emotionally connected when we hear a good story, when we could relate our own experience(s) with the person sharing his or her story and when we experience a certain feeling (happy, angry, sad etc). Stories are amazing.
