First possibility would be the affect watching a dance performance has on people. Before taking this class, I never realized the impact it can have on a person just by watching it.
Second possibility would be that dance can help our society with people that are having a hard time expressing their emotions or even just expressing themselves. I can see this after watching the videos for this class because of how emotional and powerful they were.
Third possibility would be that it can help people to get out and exercise. It could be more motivating for people because it is actually a different and more fun way of exercising and people could get into it.
