The rules of the track work well for life. Roller derby is life in a tiny circle. You can only go forward, even if you find yourself turned around, facing the wrong way. There's speed, unpredictability, and danger. You can't be sure what's going to happen, you don't always know when you'll stop, and it appears most people are out to get you. You will fall. You will get hurt. But you will get up again.
