You have waited 40 minutes for the valuable 10 minutes’ break between classes. But when the bell for the next class rings, you can’t   1   how quickly time has passed.

If you are familiar with this   2  , you’ll know how time flies when you are having fun-and  3   when you are bored. Now scientists have   4  a reason why this is the case.

Scans have shown that patterns of activity in the brain   5   according to how we focus on a task. When we are   6  , we concentrate more on how time is passing. And this makes our brains   7   the clock is ticking more slowly.

In an experiment   8   by a French laboratory, 12 volunteers watched an image   9 researchers monitored their brain activity.

The volunteers were told to   10   concentrate on how long an image appeared for, then  11   the color of the image, and thirdly, study both duration and color. The results showed that  12   was more active when the volunteers paid   13   subjects.

It is thought that if the brain is   14   focusing on many aspects of a task, it has to  15  its resources, and pays less attention to the clock.  16 , time passes without us really   17   it, and seems to go quickly. If the brain is not so active, it concentrates its   18   energies on monitoring the passing of time.   19  , time seems to drag.

Next time you feel bored   20  , perhaps you should pay more attention to what the teacher is saying!

Several years ago, while attending a communication course, I experienced a most unusual thing. The instructor asked us to list anything in our past that we felt ashamed of, guilty about or regretted. The next week he invited participants to read their lists aloud. This seemed like a very private matter, but there’s always some brave soul in the crowd who would volunteer. The man next to me raised his hand and volunteered this story:

“While making my list, I remembered an incident from high school. I grew up in a small town in Iowa. There was a Sheriff in town that none of us kids liked. One night, my two friends and I climbed the tall water tank in the middle of town, and wrote on the tank in bright red letters: Sheriff Brown is a fool. The next day, the town arose to see our glorious sign. Within two hours. Sheriff Brown had my two friends and me in his office. My friends admitted what they did and I lied, denying the truth. No one ever found out.”

Nearly 20 years later, Sheriff Brown’s name appears on my list. I didn’t even know if he was still alive. Last weekend, I dialed information in my hometown back in Iowa. Sure enough, there was a Roger Brown still listed. I dialed his number. After a few rings, I heard: “‘Hello?’ I said, ‘Sherriff Brown?’ Pause. ‘Yup.’ ‘Well, this is Jimmy Calkins. I want you to know that I did it.’ Pause. ‘I knew it!’ he yelled back. We had a good laugh and a lively discussion. His closing words were: ‘Jimmy, I always felt bad for you because your friends got it off their chest, and I knew you were carrying it around all these years. I want to thank you for calling me… for your sake.’ ”

Jimmy gave me much inspiration and I know that no matter how difficult the situation is, it is never too late to clear up the past and begin anew.
