1．Many people think it is safe to use a cell phone while they are driving．Yet Scores of studies suggest that real multitaskers-those who can carry out multiple （多个的） tasks equally well，make up just 2 percent of the population．More surprisingly，the so-called"supertaskers"actually have differently structured brains to the other 98 percent．
The brain areas that make supertaskers differ from the rest of the population are the same parts that are most different between humans and nonhuman primates （灵长类），according to David Strayer，director of the applied cognition lab at the University of Utah．Scientists are unsure of the reason why some brains are different．In fact，we could all benefit from doing just one task at once．
In most of us，scientists have located a"bottleneck in the brain"that may explain why we find it hard to do two things at once．
The problem appears to be caused by a logjam of nerve messages．Faced with two almost simultaneous （同时的） tasks less than 300 milliseconds apart，the brain's ability to deal with the second one slows down．The neural （神经的） response to the second task was postponed until the response to the first was completed．This means that with e-mails，phone calls，text messages and online social media all competing for our attention，often against a background of television，radio or music，our brains can reach information overload．
Scientists made the discovery after scanning the brains of volunteers attempting to multitask on a computer．The task was deliberately designed to involve the use of different senses and motorresponses．
Dr Rene Marois，one of the neuroscientists who carried out the experiment at Vanderbilt University in Nashville，Tennessee，said："Our research offers neurological evidence that the brain cannot effectively do two things at once．"The next step，the neuroscientists say，is finding out"why these areas cannot process two tasks at once．"

20．The 92-year-old，thin，calm and proud lady，who is fully dressed each morning by eight o'clock，even though she is nearly blind，moved to a nursing home today．
Her husband of 70years recently passed away，making the move necessary．After many hours of waiting patiently in the hall of the nursing home，she smiled sweetly when told her room was ready．
As she walked slowly to the elevator，I provided a true description of her tiny room，including the old sheets that had been hung on her window．"I love it，"she said with the happiness of an eight-year-old having just been presented with a new puppy．
"Mrs Jones，you haven't seen the room…just wait．"
"That doesn't matter，"she replied．"Happiness is something you decide ahead of time．Whether I like my room or not doesn't depend on how the furniture is arranged．It's how I arranged my mind．I have already decided to love it．It's a decision I make every morning when I wake up．Each day is a gift，and as long as my eyes open I'll focus on the new day and all the happy memories I've stored away．"She went on to explain，"Old age is like a bank account．You take what you've put in．So，my advice to you would be to put in a lot of happiness in the bank account of memories．Thank you for your part in filling my memory bank．"And with a smile，she said，"All my memories are happy ones．"
