       The regular use of text messages and e-mails can lower the IQ more than twice as much as smoking marijuana(大麻). That is the claim of psychologists who have found that tapping away on a mobile phone or computer keypad or checking them for electronic messages temporarily knocks up to ten points off the user’s IQ.

       This rate of decline in intelligence compares unfavorably with the four-point drop in IQ associated with smoking marijuana, according to British researchers, who have labeled(贴标签于，指……为，分类) the fleeting phenomenon of enhanced stupidity as “infomania”.

       The noticeable drop in IQ is believed to be the result of the constant distraction of “always on” technology when employees should be concentrating on what they are paid to do. Infomania means that they lose concentration as their minds remain fixed in an almost permanent state of readiness to react to technology instead of focusing on the tasks in hand.

       The brain also finds it hard to deal with keeping lots of tasks in motion at once, reducing its overall effectiveness. While modern technology can have huge benefits, excessive(过度的) use can be damaging not only to a person’s mind, but to his or her social life.

       Eighty volunteers took part in clinical (临床的)trials on IQ damage and 1,100 adults were interviewed.

       More than six in ten people polled admitted that they were addicted to checking their e-mails and text messages so that they examined work-related ones even when at home or on holiday. Half said that they always responded immediately to an e-mail and one in five would interrupt a meeting to do so.

       Furthermore, Informania is having a negative effect on work colleagues, increasing stress and disagreeing feelings. Nine out of ten polled thought that colleagues who answered e-mails or messages during a face-to-face meeting were extremely rude. Yet one in three Britons believed that it was not only acceptable, but actually diligent and efficient to do so.

It doesn't matter when or how much a person sleeps, but everyone needs some rest to stay alive. That's what all doctors thought, until they heard about Al Herpin. Al Herpin, it was said, never slept. Could this be true ? The doctors decided to see this strange man themselves.

Al Herpin was 90 years old when the doctors came to his home in New Jersey. They thought for sure that he got some sleep of some kind. So they stayed with him and watched every movement he made. But they were surprised. Though they watched him hour after hour and day after day. They never saw Herpin sleeping. In fact, he did not even own a bed. He never needed one.

The only rest that Herpin sometimes got was sitting in a comfortable chair and reading newspapers. The doctors were puzzled by this strange continuous sleeplessness. They found only one answer that might explain his condition. Herpin remembered some talk about his mother having been injured several days before he was born. But that was all. Was this the real reason ? No one could be sure. Herpin died at the age of 94.
