Entertaiment is a very broad term, and it’s difficult to define. It can mean anything from a personal entertainment choice to something designed for an audience of thousands. It can be a feast for the senses or a satire of society’s shortcomings. It can be an art form or a practical endeavor, such as SU2C’s model of collaboration among world-class scientists to accelerate research breakthroughs into major advances against cancer.
Entertainment can stimulate the brain to realease seratonin, dopamine and other chemicals that make people feel good. It can also touch on themes that our brains were evolved to deeply respond to, such as murder, backstabbing and other aspects of social life.
