For many people,being on the job might just sound like a picnic compared to a day at home filled with housework,meals and childcare.Even for those with a happy family life,home can sometimes feel more taxing than work.

    In a new study,researchers at Penn State University found significantly and consistently lower levels of cortisol（皮质醇）released in response to stress,in a majority of subjects when they were at work compared to when they were at home.This was true for both men and women,and parents and people without children.

    Both men and women showed less stress at work.But women were more likely to report feeling happier there. Men were more likely to feel happier at home.Experts say there are other reasons why work is less stressful than home for many."Paid work is more valued in society,"says Sarah Damaske,the lead researcher on the study. "Household work is boring and not particularly rewarding."

    We get better at our job with time and the increased competence means less stress and more rewards.Yet none of us,no matter how long we've been doing it,ever truly feels like an expert at parenting or even at marriage.

    The support and friendship of co-workers also offer stress relief.At home,meanwhile,stress spreads and accumulates（积累）quickly."That's the reason why most housewives wish they were the bread earners,"Dr.Damaske says.

    Much of the advice to families and couples include the warning to "leave work stress at the office" and even to change our mind-set from work to home,for example,a walk around the block.The recent findings,though,suggest  our home life,not our attitude,might be due for some change.

    Welcome to your future life!

    You get up in the morning and look into the mirror. Your face is firm and young-looking. In 2035, medical technology is better than ever. Many people your age could live to be 150, so at 40, you're not old at all. And your parents just had an anti-aging(抗衰老的) treatment. Now, all three of look the same age!

    You say to your shirt, “Turn red.” It changes from blue to red. In 2035, “smart clothes” contain particles(粒子) much smaller than the cells in your body. The particles can be programmed to change clothes' color or pattern.

    You walk into the kitchen. You pick up the milk, but a voice says,“ You shouldn't drink that!” Your fridge has read the chip (芯片) that contains information about the milk , and it knows the milk is old . In 2035, every article of food in the grocery store has such a chip.

    It's time to go to work. In 2035, cars drive themselves. Just tell your “smart car” where to go. On the way, you can call a friend using your jacket sleeve. Such “smart technology” is all around you.

    So will all these things come true? “For new technology to succeed,” says scientist Andrew Zolli ,”it has to be so much better that it replaces what we have already.” The Internet is one example—what will be the next?

    Are you looking for some new and exciting places to take your kids to? Try some of these places.

    Visit art museums. They offer a variety of activities to excite your kids' interest. Many offer workshops for making hand-made pieces, traveling exhibits, book signings(签名) by children's favorite writers, and even musical performances and other arts.

    Head to a natural history museum. This is where kids can discover the past from dinosaur(恐龙) models to rock collections and pictures of stars in the sky. Also, ask what kind of workshops and educational programs are prepared for kids and any special events that are coming up.

    Go to a Youtheater. Look for one in your area offering plays for child and family visitors. Pre-show play shops are conducted by area artists and educators where kids can discover the secret about performing arts. Puppet(木偶) making and stage make-up are just a couple of the special offerings you might find.

    Try hands-on science. Visit one of the many hands-on science museums around the country. These science play-lands are great fun for kids and grown-ups alike. They'll keep your child mentally and physically active the whole day through while pushing buttons, experimenting, and building. When everyone is tired, enjoy a fun family science show, commonly found in these museums.

    A 12-year-old with end stage cancer, the child's parents had recently moved her from the hospital to her home in the suburbs of Los Angeles. Some days later the girl's breath quickened, and her father phoned the family's hospice nurse. Please come, he said.

    The nurse knew the visit would require more than four hours of her time: a two-hour drive in each direction, plus her time with the girl. Why don't we connect over FaceTime, she asked. The father agreed, and they connected.

The nurse asked the father to move his daughter gently to her side, then to her back, to lift the child's shirt. The nurse would ask: What do you see, what concerns you, and the father would explain. In this fashion the pair examined the girl — the nurse on her computer, the father his iPad. Together they decided that the nurse's presence was not necessary, that the child had more time.

    Later, the father reported feeling comforted by the nurse. He appreciated her availability, the fact that she could see what he saw, and their ability to discuss it in real time.

Telemedicine has become a trend in America. Some hospitals have gone so far as to specially design telemedicine clinics. The room is staged like an office but with better lighting. There's a nice desk for the clinician to sit behind, a computer situated stage left, and books in the background. A physician taking a video call from home might wear a pair of headphones, equipped with a mic — to ensure whatever the patient says isn't broadcast to anyone off-camera.

    However, there is something more than the technology bit. According to David, the head of the telemedicine pilot the girl's family had been part of, there are some people who are great in person and you put them on camera they're a dead fish. “Some physicians are camera shy. For others, the physical isolation can actually help them be more empathetic.” He adds.

    “My experience is that, once you get past some initial hurdles, you can maintain an intimate, immediate connection with patients that in some cases may be more useful than even in-person interactions,” David says.

    If you could have a superpower, what would it be? Other than flying and communicating with someone from his mind (which, let's be honest, would probably actually be awful), breathing underwater is one of the favorites. You can hang out with Aquaman and Ursula, and when the end of the world comes and we're all living under water, you'll be fine.

    With this in mind, a student at the Royal College of Art, London has designed a 3D-printed amphibious garment called AMPHIBIO —essentially a set of gills (鳃) —for this very purpose. According to Jun Kamei, a biomimicry designer and materials scientist, it is "for a future where humankind lives in the water".

    With the world set for a global temperature increase of 3. 2℃ (5. 7℉) by 2100, rising sea levels are a very real threat to large coastal cities, potentially affecting up to 2 billion people —or 26 percent of the current global population.

    Kamei's little device uses a specially designed porous (多孔的) material that fills oxygen again in the water and releases carbon dioxide. It is inspired by water-diving insects that create their own little scuba diving set by creating a protective bubble of air around their body thanks to their water repellent (防水的) skin.

    The technology is easily 3D-printable too, which will be great when we need them together. These "gills" could replace heavy and clumsy scuba equipment, making it more similar to free diving but for longer. This could have immediate applications for underwater rescue plans —the 12 boys rescued by divers from a flooded cave in Thailand, for example, where it took weeks to work out how to get the boys and the vital breathing equipment through those narrow tunnels.

    So far, the tech has only been tested as a working prototype, not actually on humans, so the dream may have to be on hold for now. And scaling up and testing on humans is Kamei's next plan. This may sound unbelievable, but Kamei insists he has a much more optimistic vision of the future.

    Not many years ago, a wealthy and rather strange old man named Johnson lived alone in a village in the south of England. He had made a lot of money in trading with foreign countries. When he was seventy – five, he gave $ 60,000 to the village school to buy land and equipment for a children's ground.

    As a result of his kindness, he became famous. Many people came to visit him. Among them was a newspaperman. During their talk, Johnson remarked that he was seventy-five and expected to live to be hundred. The newspaperman asked him how he managed to be healthy at seventy-five. Johnson had a sense of humor. He liked whisky and drank some each day. "I have an injection (注射) in my neck each evening," he told the newspaperman, thinking of his evening glass of whisky.

    The newspaperman did not understand what Johnson meant. In his newspaper he reported that Johnson was seventy-five and had daily injection in his neck. Within a week Johnson received thousands of letters from all over Britain, asking him for the secret of his daily injection.
