Imagine you are in a football game against a highly superior team. It is almost 10 minutes before the game ends, and you are currently losing 0-1. They keep attacking your goal and each attempt on goal would seem to produce goal which would end your game immediately. What would you do?
It is easy to say that we going to keep fighting at that point. But with all the emotion and stress, doesn't seem so easy. Mathematically (ok, I hate math, so please someone do the math for me), you will lose anyway. But just keep in mind that the game isn't ended yet.
So just keep fighting. Until you lose anyway. Or win.
