Article: Long after the 1998 World Cup was won, disappointed fans were still cursing the disputed refereeing decisions that denied victory to their team. A researcher was appointed to study the performance of some top referees. The researcher organized an experimental tournament involving four youth teams. Each match lasted an hour, divided into three periods of 20 minutes during which different referees were in charge. Observers noted down the referees' errors, of which there were 61 over the tournament. Converted to a standard match of 90 minutes, each referee made almost 23 mistakes, a remarkably high number. The researcher then studied the videotapes to analyse the matches in detail. Surprisingly, he found that errors were more likely when the referees were close to the incident. When the officials got it right, they were, on average, 17 meters away from the action. The average distance in the case of errors was 12 meters. The research shows the optimum distance is about 20 meters. There also seemed to be an optimum speed. Correct decisions came when the referees were moving at a speed of about 2 meters per second. The average speed for errors was 4 meters per second. If FIFA, football's international ruling body, wants to improve the standard of refereeing at the next World Cup, it should encourage referees to keep their eyes on the action from a distance, rather than rushing to keep up with the ball, the researcher argues. He also says that FIFA's insistence that referees should retire at age 45 may be misguided. If keeping up with the action is not so important, their physical condition is less critical.

Article: If you have ever been discouraged because of failure , please read on. Usually, achieving what you set out to do is not the important thing. Let me explain. Two brothers decided to dig a deep hole behind their house. As they were working, a couple of older boys stopped by to watch. "What are you doing?" asked one of the visitors. "We plan to dig a hole all the way through the earth!" one of the brothers answered excitedly. The older boys began to laugh, telling the younger ones that digging a hole all the way through the earth was impossible. After a long silence, one of the diggers picked up a jar full of spiders , worms and a lot of insects. He removed the lid and showed the wonderful contents to the visitors who were laughing at them. Then he said quietly and confidently, "Even if we don't dig all the way through the earth, look what we found along the way!" Their goal was far too difficult, but it made them dig. And that is what a goal is for--to make us move in the direction we have chosen. In other words, it sets us to digging! But not every goal will be fully achieved. Not every job will end successfully. Not every hope will come to pass. Not every love will last. But when you fall short of your aim, perhaps you can say, "Yes, but look at what I found along the way! Look at the wonderful things which have come into my life because I tried to do something!" And I believe it is the joy in the journey, in the end, that truly matters.
