Entertainment is a type of activity that stimulates the brain to release seratonin, dopamine and other chemicals. This helps to stimulate the mind in order to function well and deal with a social world where you need to interact and solve problems. Some people consider entertainment as a way to have fun and unwind, but it is also important because it can help families grow closer together. This is especially true in the case of children and teenagers who need to learn how to be social with one another.
