NEW YORK - People who keep doing some work in their field after they retire may enjoy better physical and mental health than those who stop work completely or switch to another area of work, according to a U.S. study.

Researchers from the University of Maryland said the findings suggest that prospective retirees should consider moving into so-called "bridge employment" as a transition to full retirement.

"In essence, if someone is in a field where part-time work or self-employment is possible, he or she should consider it as they plan for retirement," researcher Dr. Mo Wang, an assistant professor of psychology, told Reuters Health.

For their study, Wang and his colleagues used data on more than 12,000 workers in a U.S. health study begun in 1992. Participants, who were between the ages of 51 and 61 at the outset, were surveyed every two years over a six-year period.

Overall, Wang's team found, people who went into some form of bridge employment reported lower rates of major diseases like high blood pressure, heart disease, diabetes and arthritis during the study period than their counterparts who went straight into full retirement.

The findings were not explained by older age or worse initial health among people who opted for full retirement, the investigators report in the Journal of Occupational Health Psychology.

On top of their better physical health, "bridge" workers also tended to report fewer mental health problems, such as depression.

The same mental health benefits were not seen, however, when retirees took part-time work in other fields -- possibly, Wang said, because many of these people may have taken those jobs out of financial need rather than choice.

He noted that the lack of benefit could also stem from the fact that these retirees had to adjust to an unfamiliar job position or had to make lifestyle changes.

Bridge work, particularly in one's accustomed field, may benefit physical and mental health for a number of reasons, according to Wang.

In general, he explained, such work may help older adults maintain the active lifestyles they had during their careers and decrease any stress they might feel from the transition into retirement.  wwwWang said when it comes to mental health, for instance, bridge work may help by allowing people to keep some of the "role identity" that they have formed over their careers.

Staying active in general, not only through work, can also benefit retirees' physical health, Wang noted. He added, however, that any mental health benefits are likely to depend on the type of activity -- whether it is something that the person truly enjoys, and that helps ease any stress of moving into retirement.

"These findings," Wang said, "suggest that for retirees and prospective retirees, carefully considering whether to engage in bridge employment -- and if so, what types of bridge employment -- is quite important."

You want a smart phone， but just how smart do you want it？ How about one that can read your mind？ Well， that phone may well be on its way...

Justin Rattner， chief researcher at Intel， says that technology has developed to the point that “context-aware computing (情景感知计算)”， an idea that’s been around for twenty years， is becoming more of a reality.

That could lead to a phone that acts as a mind reader in your pocket. But rather than simply collect secrets about you， the device could do things with that information， such as predict what you might do next and make suggestions.

Rattner gave a few examples during his speech at Intel’s developer conference in San Francisco recently.

Among them is a software that Intel worked on with Fodor’s Travel， a traveling website. It learns what types of foods you like to eat and what types of places you like to visit， based on searches you type into the phone or places you searched using GPS (全球定位系统). The software makes similar recommendations when you visit a new city.

Tech companies are already working to predict what people want. Search engine Google， movie-rental service Netflix， and online radio service Pandora try to guess what people want even before they know they want it.

Putting those types of functions together with the other information that phones collect about people could pave the way for even more helpful mobile phones， Rattner said.

A challenge is training computers to look at data from “hard sensors (传感器)” (which measure place， movement， temperature and the like) and combining those findings with data from “soft sensors” (such as calendar appointments and Web browsing history).

For example， your phone could tell that you have just left school and seem to be on your way home—a location it might know from your address book. It could then tell you the best route around traffic.

Rattner added that researchers are even making steps toward the final goal—a computer understanding of thoughts.

Moving should be an exciting time — you’re off to a new home, maybe moving up to a larger home. But for many people, moving turns into a stressful experience. It doesn’t have to be that way. Some planning and a little research can make your next move the best one ever.
Organization is the key to a successful move, so lists are your friends. Write down all the details that you need, especially things that might be lost during the move.
Once you decide to move, start packing things immediately. You can find all the supplies you need, such as boxes, packing tape and more at truck rental outlets (租赁经销店) like Budget Truck Rental. The experts there can help you figure out how many and what types of boxes you’ll need.
About a month before your moving date, reserve (预定) your moving truck. The company you choose makes a big difference. Budget Truck Rental has 30,000 trucks nationwide for you to choose.
Take care of your mail. Stop by your local post office and write the new address where your mail should be sent. You’ll also want to change the address on any magazine subscriptions (订购) or other services you receive by mail.
Make sure you have a group of friends to help you move. If you still have some boxes to pack, your friends can help you put the boxes into the truck while you finish up.
