Fashion treadmill desks (跑步机办公室) might actually help improve job performance after employees get used to working while walking, according to new research.

A yearlong study of workers at a company St. Paul, Minn, found that the productivity of 40 treadmill users dropped at first because they were unable to master typing and operating a mouse while walking at a speed of up to two miles per hour.

But within four to six months, measures (测量) of performance-quality, the amount of work done, and the quality of interactions(互动) with workmates rose gradually, according to weekly surveys. At the end of the survey period, workers with treadmill desks improved their performance, which was 0.69 points higher than that before the project began.

For tasks like solving problems or taking conference calls, “ A little bit of walking is useful because it means there’s more blood flow to the brain,” said Avner Ben-Ner, a professor at the University of Minnesota’s Carlson School of Management and an author of the study. “ You get more oxygen (氧气) and it increases the ability to think .”

Treadmill desks have got attention because of research which showed the negative (负面的，消极的)effects of sedentary lifestyles and jobs that leave workers sitting all day. But data on the effectiveness of the desks has been relatively rare.

There are other downsides (不利方面) , as The Wall Street Journal wrote last year, including the possibility of falls and injuries.

Mr. Ben-Ner noted that treadmill users need some time to get used to the ergonomics (人体工程学) of walking while working, including the proper desk height. His team provided no training to employees, and he said that employers who provide such desks should offer help to get users comfortable on the machines.

“This wouldn’t be very good for people who use a needle for their jobs,” he said. “ But everyone who does brain work knows that if you need fresh ideas, taking a walk helps.”

She had been shopping with her Mom in Wal-Mart. She must have been 6 years old, beautiful and innocent*. Outside, it was pouring so heavily.

We all stood there just inside the door of the Wal-Mart. We waited, some patiently, others annoyed because nature messed up their hurried day. I got lost in the sound and sight of the heavens washing away the dirt and dust of the world.

Her voice was so sweet that it woke me up.

“Mom, let’s run through the rain,” she said.

“No, honey. We’ll wait until it slows down a bit,” Mom replied.

Waiting about another minute, the young child repeated: “Mom, let’s run through the rain. ”

“We’ll get soaked if we do,” Mom said.

“No, we won’t, Mom. That’s not what you said this morning,” the young girl said, pulling her Mom’s arm.

“This morning? When did I say we could run through the rain and not get wet?”

“Don’t you remember? When you were talking to Daddy about his cancer*, you said if God can get us through this, he can get us through anything!”

All the people stopped dead silent. You couldn’t hear anything but the rain. No one came or left in the next few minutes. Mom paused and thought for a moment about what she would say.

Now some would laugh it off or tell her not to be silly. Some might even pay attention to what was said. But this was a moment in a young child’s lifetime that some innocent trust may bloom into faith. “ Honey, you are right. Let’s run through the rain. If get wet, well, maybe we just need washing, ” Mom said. Then off they ran.

We all stood watching, smiling and laughing as they rushed past the cars and they held their shopping bags over their heads just in case. They got soaked. But they were followed by a few who screamed and laughed like children all the way to their cars. And yes, I did. I ran. I got wet. I needed washing.

You may lose what you have, your money and even your health, but no one can ever take away your valuable memories. So don’t forget to make time and take the chance to make memories.

One of the problems with passwords is that users forget them. In order to remember them, people use simple things like their dog’s name, their birth date, or the name of the current month-anything that will give them a clue to remember what their password is.

For the curious hacker (黑客) who has gained access to your online account, this is the same as locking your door and leaving the key under the doormat (门垫).

To create a safe password that is easy to remember, follow these simple steps:

● You should never use personal information as part of your password. It is very easy for someone to guess things like your last name, pet’s name, child’s birth date and other similar details.

● There are tools available to help attackers guess your password. With today’s computing power, it doesn’t take long to try every word in the dictionary and find your password, so it is best if you do not use real words for your password.

● You can make a password much safer by mixing different types of characters. Use some uppercase letters (大写字母) along with lowercase letters (小写字母), numbers and even special characters such as “&” or “%”.

● Rather than trying to remember a password that is created using various character types and is not a word from the dictionary, you can use a “passphrase”. Think of a sentence or a line from a song or poem that you like and create a password using the first letter from each word.

For example, rather than just having a password like “yr $ 1 Hes”, you could take a sentence such as “I like to read the About. Com Internet network security website” and convert it to a password like “il2rtA! nsws” by using the number “2” for the word “to” and using an exclamation point (感叹号) in place of the “I” for “Internet”. You can use a variety of character types and create a safe password that is hard to figure out, but much easier for you to remember.

● You should use a different username and password for each login you’re trying to protect. That way, if someone figures out one of your passwords, the others are still safe. Another approach, which is less safe, but provides a fair balance between security and convenience, is to use one username and password for sites and applications that don’t need the extra security, but use unique usernames and more safe passwords on sites that require more security, such as your bank’s website.
