When we are 26 , we concentrate more on how time is passing. And 27 makes our brains think the clock is ticking more slowly.In an experiment 28 by a French laboratory, 12 volunteers watched an image 29 researchers monitored their brain activity.The volunteers were told to 30 concentrate on how long an image appeared for, then 31 the color of the image, and thirdly, study both duration and color. The results showed that 32 was more active when the volunteers paid attention to 33 subjects.It is thought 34 if the brain is focusing on many aspects of a task, it has to 35 its resources, and pays less attention to the clock. 36 , time passes without us really 37 it, and seems to go quickly.
