What do you do when the unexpected happens?

2004 Athens Olympic Marathon game. When an attacker came out of nowhere and pushed him off the running course and into the crowd, the Brazilian Marathon runner collected himself and moved on quickly. Not only did he finish the game, he ended up winning a bronze medal. He was also gracious enough to do a plane run right before the finish line. That was a moving moment.

When the audience protested the judges for lowscoring the Russian gymnast's routine for a long few minutes, Paul Hamm remained focused on his own game and eventually won the gold metal.

Have unexpected things happened to you before? How did you react? Did you let it affect you in a negative way? Were you so engrossed in your emotions about getting even? Were you so stuck about the why why why that you lost productivity?

Or
Did you collect yourself quickly and remained cool and focused on the task at hand?

I'd vote for the latter.

I want to know what went thru Paul's mind? What went thru the Brazilian mind when these unexpected and often potentially negative things happened to them.

I'd like to model my thinking after them.
