“Sugar, alcohol and tobacco,” economist Adam Smith once wrote, “are commodities which are nowhere necessaries of life, which have become objects of almost universal consumption, and which are, therefore, extremely popular subjects of taxation.”

    Two and a half centuries on, most countries impose (征税) sort of tax on alcohol and tobacco. With obesity levels putting increasing pressure on public health systems, governments around the world have begun to toy with the idea of taxing sugar as well.

    Whether such taxes work is a matter of debate. A preliminary review of Mexico's taxation found a fall in purchases of taxed drinks as well as a rise in sales of untaxed and healthier drinks. By contrast, a Danish tax on foods high in fats was abandoned a year after its introduction, during claims that consumers were avoiding it by crossing the border to Germany to satisfy their desire for cheaper, fattier foods.

    The food industry has, in general, been firmly opposed to such direct government action. Nonetheless, the renewed focus on waistlines means that industry groups are under pressure to demonstrate their products are healthy as well as tasty.

    Over the past three decades, the industry has made some efforts to improve the quality of its offerings. For example, some drink manufactures have cut the amount of sugar in their beverages (饮料).

    Many of the reductions over the past 30 years have been achieved either by reducing the amount of sugar, salt or fat in a product, or by finding an alternative ingredient. More recently, however, some companies have been investing money in a more ambitious undertaking: learning how to adjust the fundamental make-up of the food they sell. For example, having salt on the outside, but none on the inside, reduces the salt content without changing the taste.

    While reformulating (再制定) recipes is one way to improve public health, it should be part of a multisided (多边的) approach. The key is to remember that there is not just one solution. To deal with obesity, a mixture of approaches, which include reformulation, taxation and adjusting portion sizes, will be needed. There is no silver bullet.

    Climbing Without Ropes

    The popular image of the mountain climber is of a person carefully climbing a steep cliff with a network of safety ropes, but it is not the only kind. Many climbers now enjoy bouldering. It's more accessible and better for the environment.

    Here is an example of a climber addressing a bouldering problem.

    Figure 1: The climber has two routes she could take, one to the left and one to the right. The left one appears easier because it has a jug within easy reach, but look what happens if she chooses that direction. She gets stuck on the rock and has to go back down. Sometimes that is even more difficult than going up.

    Figure 2: The climber takes the one to the right this time. Using a foothold and placing her right hand in a crimp, she is able to lift herself up and locate other handholds. After only a few moves, she is able to throw her leg over the top of the boulder and pull herself up.

    Shine United (Madison, Wisconsin)

    In the past five years, this Wisconsin-based advertising agency has shared more than $500,000 in profits with its employees through the company's ShineShares program. The agency partnered with the University of Wisconsin's oncology department to develop the Ride, a biking event that benefits cancer research. Employees also get snacks every day, “Beer Thirty” on Thursdays, and Summer Fridays, a program that lets employees leave at noon.

    GroundFloor Media (Denver, Colorado)

    The key for workers at this midsize public relations firm in Denver is that employees work anytime, anywhere. Headquarters are in a former warehouse downtown, near Coors Field. The offices are spread around the central space that doubles as a wet bar every Thursday when the company's “bear club” brings in a new brew.

    Ergodyne (St. Paul, Minnesota)

    The St. Paul-based company has grown to operating out of a retired storehouse with plenty of natural light. Rules about dressing? “Wear something.” Its purpose? To create cool, comfortable, and tough safety workwear for those who need it to get the job done. Ergodyne has around 50 employees, who enjoy hot-dish cook-offs, tickets to sporting events, and at least one happy hour every quarter.

    Southwest Michigan First (Kalamazoo, Michigan)

    It's family first at this Michigan economic development advising agency. CEO Ron Kitchens says that in the past year, the company has made a push to go green, initially started by the millennial employees who make up half the agency's workforce. A new staff position was created for the purpose of making sure every employee is able to balance working and cheering at their kids' sporting events or going fishing.

    If you want to convince the boss you deserve a pay rise or promotion, the solution could be simple—eat the same food as they do.Psychologists have discovered managers are much more likely to instantly trust us if we choose the same dishes as them.

    During experiments, discussions over wages and work conditions were much more successful if both sides chose to snack on the same treats.And shoppers were much more likely to buy a product advertised on TV by someone eating a similar food to them at the time.

    The reason is thought to be so­called similarity attraction theory—where people tend to like others who have similar tastes or habits to themselves.But this is believed to be one of the first studies highlighting the role of food in this relationship.Researchers at Chicago University in the US conducted a series of experiments to examine food's role in earning trust.

    In a test, participants were told to watch TV—where someone pretending to be a member of the public praised a certain product.The volunteers were given Kit Kat bars to nibble, while the TV people ate either a Kit Kat or grapes as they talked.

    The results showed viewers were much more likely to express an interest in buying the product if the TV showed the other person eating a Kit Kat too.

    The researchers added, “Although similarity in food consumption is not a sign of whether two people will get along, we find consumers treat this as such.They feel more trusting of those who consume as they do.It means people can immediately begin to feel friendship and develop a bond, leading to smoother transactions from the start.”

    Harley Street psychologist Dr.Lucy Atcheson said it was already known that wearing similar clothes could instantly create trust.But this was the first report that food had the same effect.She said, “This is really interesting.It makes sense as people feel they have common ground and can trust the other person.That means negotiations are more likely to be successful.”

    I left university with a good degree in English Literature, but no sense of what I wanted to do. Over the next six years, __________ just trying to earn an income. I tried journalism, but I didn't think I was any good, then finance, which I hated. Finally, I got a job as a rights assistant at a famous publisher. I loved working with books, although the job that I did was dull.

    I had enough savings to take a year off work, and I decided to try to satisfy a deep-down wish to write a novel. Attending a Novel Writing MA course gave me the structure I needed to write my first 55,000 words.

    It takes confidence to make a new start — there's a dark period in-between where you're neither one thing nor the other. You're out for dinner and people ask what you do, and you're too ashamed to say, "Well, I'm writing a novel, but I'm not quite sure if I'm going to get there." My confidence dived. Believing my novel could not be published.

    I put it aside.

    Then I met an agent(代理商)who said I should send my novel out to agents. So, I did and, to my surprise, got some wonderful feedback. I felt a little hope that I might actually become a published writer and, after signing with an agent, I finished the second half of the novel.

The next problem was finding a publisher. After two-and-a-half years of no income, just waiting and wondering, a publisher offered me a book deal — that publisher turned out to be the one I once worked for.

    It feels like an unbelievable stroke of luck — of fate, really. When you set out to do something different, there's no end in sight, so to find myself in a position where I now have my own name on a contract of the publisher — to be a published writer — is unbelievably rewarding.
