Have you ever had the strange feeling that you were being watched? You turned around and, sure enough, someone was looking right at you!

Some parapsychologists （心理學(xué)家） say that humans have a natural ability to sense when someone is looking at them. To study whether such a "sixth sense" really exists, Robert Baker, a psychologist at the University of Kentucky, performed several experiments.

In the first one. Baker sat behind unsuspecting people in public places and stared at the backs of their heads for 5 to 15 minutes. The subjects were eating, drinking, reading, studying, watching TV, or working at a computer. Baker made sure that the people could not tell that he was sitting behind them during those periods. Later, when he questioned the suspects, almost all of them said they had no' idea that someone was staring at them. 

For the second experiment. Baker told subjects that they would be stared at from time to time from behind a two-way minor in a lab setting. The people had to write down when they felt they were being stared at and when they weren’t. Baker found that the subjects were no better at telling when they were stared at than if they had just guessed.

Baker’s experiment concludes again that people do not have the ability to sense when they are being stared at. If you doubt the outcome of his two experiments, I suggest you repeat the experiments and see for yourselves.

Patricia Blues, 29, has a new aim in life: to keep drivers' hands on their steering wheels and off their cell phones. On November 2, 2007, Blues lived through a horrible experience. A motorist dialing a cell phone drove through a stop sign at 45 miles per hour and run into the side of Blues' car. Blues' 2-year-old daughter was killed immediately in the crash.

Blues has since dedicated her time to pushing for laws that would prevent this type of tragedy from happening again.

Cell phones are not the only distractions (分神) that cause accidents. Eating, changing CD, reading maps, talking to passengers, and just reaching for an object on the floor can be dangerous. Therefore, the emphasis should be on educating drivers to avoid all distractions. However, talking on cell phones might be easier to regulate than eating or changing music. At least 34 states have already passed laws to restrict cell phone use in moving cars. No state has banned it yet, but several U. S. cities have. Worldwide, 13 nations, including Australia, England, Germany, Japan and China have banned drivers' use of cell phones in moving cars.

To date, no scientific evidence has been published showing that talking on the phone affects driving safety. But according to a test by some high school students, "driving while on the phone does affect safety and probably shouldn't be done".
