You are driving down the highway when you encounter a sign that reads, “Dangerous Curve Ahead.” Immediately you are confronted with making a choice. One, you can observe the warning and slow down. Two, you can ignore the warning and maintain your rate of speed. Or, three, you can defy the warning and speed up. Whatever response you exercise, you will not change the truth of the sign. The curve remains dangerous, regardless of whether you acknowledge the fact or not.
