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.

    Last week, my granddaughter started kindergarten, and I wished her every success. But part of me didn't. I actually wanted her to fail in some ways because I believe that failure can be good for our learning process. Success is proving that you can do something that you already know you can do, or doing something correctly the first time, which can often be a problematic (存在问题的) victory. First-time success is usually a fluke (侥幸). First-time failure, however, is supposed to be the natural order of things. Failure is how we learn.

    In Africa they describe a good cook as “She who has broken many pots.” If you've spent enough time in the kitchen to have broken a lot of pots, probably you know a fair amount about cooking. I once had dinner with a group of cooks, and they spent time comparing knife wounds and burn scars. They knew how much credibility (可信) their failures gave them.

    I earn my living by writing a daily newspaper column. Each week I know that one column I write is going to be the worst column. I try my best every day. I have learned to love that column. A successful column usually means that I am discussing my familiar topic, writing in a style I am used to or saying the same things as anyone else but in a better way.

    My younger daughter is a trapeze artist (荡秋千演员). She spent three years practising a show, and she did it successfully for years. There was no reason for her to change it but she did anyway. She said she was no longer learning anything new and she was bored. And if she was bored, there was no point in subjecting (使……服从于) her body to all that stress. She risked failure and great public embarrassment in order to feed her soul.

    My granddaughter is a perfectionist. She will feel her failures, and I will want to comfort her. But I will also, I hope, remind her of what she learned, and how she can do better next time. I hope I can tell her, though, that it's not the end of the world. Indeed, with luck, it is the beginning.

    I was on my school campus the other day, and there was an ice cream truck parked right in front of the main common areas of the school. I had never thought an ice cream truck would circle our campus and come for us, overgrown kids. I was intrigued and wanted to investigate（调查）further.

    I was quite surprised when the man in the truck called out,“ Free ice cream!”

    I questioned him just to make sure of his words, saying," I' m sorry, what did you say?"

    “Free ice cream. You have your choice of these four frozen treats: the rocket pop, the chocolate Eclair, the strawberry shortcake, or the drumstick.”

    After I was certain that the man was just giving away free ice cream, I talked with him for a while. He told me that his dream had always been to travel around giving away ice cream, and that's exactly what he did. And his passion was expressed through using up all his credit cards, sleeping in his truck, and living with his mother in a small flat, so he could continue to follow his dream during hard times .Now, he has sponsorships（赞助）from large companies such as Levi's to do what he loves, and he's gifted 125,000 of his truckload of ice cream treats!

    The man said he wanted to encourage people to do exactly what their hearts tell them to do with their lives. I kept asking him with respect," So your dream was just to drive around and give away ice cream? It seems like a very unusual goal."

    "Yes ,just meeting people and making them smile," he replied.

    I absolutely love Bark magazine! I love the “smiling” pages and the tips on every issue. I am a dog lover and have saved all of my dogs from either death row or from people who were going to put them down. Everyone should have a chance to live and Bark stresses that with its articles.

    Don't waste your money on this magazine. 60-70 percent of it are advertisements, and the articles offer little useful information. It might be suitable for children, but not adults who are serious about educating themselves about dogs.

    Dog World has many very interesting and thought-provoking (令人思考的) articles for people involved in dog showing, breeding(饲养), performance events, etc. However，over half of the magazine is devoted to breeder ads, which is boring. Still, as a whole, I recommend(推荐) it for the articles. Good articles, but tons of ads.

    My new favorite magazine! Beautiful photos, smart and amusing articles, fashion, art, interviews with famous people… all with a dog focus！Cover models range from Paris Hilton and Tinkerbell to Virginia Madsen and her dogs. Thanks to Modern Dog I now know how to give a dog-friendly cocktail party and how to actually get my dog to come when she's called. Surely worth checking out.

    Employers and managers must never ignore the need for an office or industrial first aid kit. The federal government says that every workplace should be equipped with first aid kits and that employees should be taught first aid.

    Good preparation can prevent unnecessary injury, lose of productivity(生产效率), or even law suits when a workplace emergency occurs.

    An employer must first provide the proper number of first aid kits for his workers. Many kits are available for sale online by industrial first aid kit suppliers. Kits designed for ten workers cost about $15 and kits designed for fifty workers cost about $80. There are kits also available for a small office，a vehicle，or work sites. Kits should be stored in a portable(轻便的), durable, watertight container. Fix the kit to the wall so that it is easily seen and reached in an emergency. Include a list of kit's contents to ensure it is always fully stocked.

    Show each worker where the kit is located and what tools it contains. Educate each worker about possible injuries and which ones will require immediate medical attention from professionals.

    The American Red Cross sells industrial first aid kits that meet the United States' Occupational Safety and Health Administration's requirements. Several types of kits are available. The Personal Protection Kit contains gloves, gowns, and masks to protect workers from dangers like blood and bodily fluids. It costs about $15. The American Red Cross also sells industrial first aid kits for 25 or 50 workers that are both very cheap.

    Stocky, slow-moving whale, rarely grows beyond 15 metres in length

    Flippers are a third of body length; variable dorsal fin size and shape; saw-toothed trailing edge on flukes, often raised when diving

    Bumpy tubercles on top of head

    Body colour is dark brown to black; often extensive white on flippers and underside of body and flukes; such patterns enable individual recognition

    Bushy blow, occasionally V-shaped

    270-400 olive baleen plates

    Humpback whales belong to the rorqual (groove-throated) family, which includes fin, sei, Bryde's, minke and blue whales. The big family migrate between winter tropical breeding areas (North West Shelf, Great Barrier Reef, New Caledonia, Vanuatu, Fiii, Tonga) and summer Antarctic feeding areas. Once common in New Zealand waters, humpbacks are now rarely seen and may migrate further offshore. Males compete for mates either by physical fight or by song. Females give birth to their young every two to three years; some non-breeding females probably remain in the southern waters during winter. Young humpback whales return to their area of birth but in later life some wander between breeding areas. Humpbacks eat small shrimps and other schooling prey, such as fish, forming small, cooperative groups of two to three individuals to feed.

    Similar species: Easily identifiable due to a 'hump' back when submerging, but at a distance may be confused with other species that raise their flukes when diving, such as sperm, right and blue whales.

    Protection status: Recovering well from past whaling and now numerous in some former migration and aggregation areas, rarely seen in others.
