When Microsoft bought task management app Wunderlist and mobile calendar Sunrise in 2015, it picked up two newcomers that were attracting considerable buzz in Silicon Valley. Microsoft’s own Office dominates the market for “productivity” software, but the start-ups represented a new wave of technology designed from the ground up for the smartphone world.Both apps, however, were later scrapped, after Microsoft said it had used their best features in its own products. Their teams of engineers stayed on, making them two of the many “acqui-hires” that the biggest companies have used to feed their insatiable hunger for tech talent.To Microsoft’s critics, the fates of Wunderlist and Sunrise are examples of a remorseless drive by Big Tech to chew up any innovative companies that lie in their path. “They bought the seedlings and closed them down,” complained Paul Arnold, a partner at San Francisco-based Switch Ventures, putting an end to businesses that might one day turn into competitors. Microsoft declined to comment.Like other start-up investors, Mr. Arnold’s own business often depends on selling start-ups to larger tech companies, though he admits to mixed feelings about the result: “I think these things are good for me, if I put my selfish hat on. But are they good for the American economy? I don’t know.”The US Federal Trade Commission says it wants to find the answer to that question. This week, it asked the five most valuable US tech companies for information about their many small acquisitions over the past decade. Although only a research project at this stage, the request has raised the prospect of regulators wading into early-stage tech markets that until now have been beyond their reach.Given their combined market value of more than $5.5 trillion, rifling through such small deals—many of them much less prominent than Wunderlist and Sunrise—might seem beside the point. Between them, the five biggest tech companies (Apple, Microsoft, Google, Amazon and Facebook) have spent an average of only $3.4 billion a year on sub—$1 billion acquisitions over the past five years—a drop in the ocean compared with their massive financial reserves, and the more than $130 billion of venture capital that was invested in the US last year.However, critics say that the big companies use such deals to buy their most threatening potential competitors before their businesses have a chance to gain momentum, in some cases as part of a “buy and kill” tactic to simply close them down.1. What is true about Wunderlist and Sunrise after their acquisitions?2. Microsoft’s critics believe that the big tech companies tend to ___.3. Paul Arnold is concerned that small acquisitions might _.4. The US Federal Trade Commission intend to _.5. For the five biggest tech companies, their small acquisition have ___.

With the global population predicted to hit close to 10 billion by 2050, and forecasts that agricultural production in some regions will need to nearly double to keep pace, food security is increasingly making headlines. In the UK, it has become a big talking point recently too, for a rather particular reason: Brexit.Brexit is seen by some as an opportunity to reverse a recent trend towards the UK importing food. The country produces only about 60 per cent of the food it eats, down from almost three-quarters in the late 1980s. A move back to self-sufficiency, the argument goes, would boost the farming industry, political sovereignty and even the nation’s health. Sounds great—but how feasible is this vision?According to a report on UK food production from the University of Leeds, 85 percent of the country’s total land area is associated with meat and dairy production. That supplies 80 per cent of what is consumed, so even covering the whole country in livestock farms wouldn’t allow us to cover all our meat and dairy needs.There are many caveats to those figures, but they are still grave. To become much more self-sufficient, the UK would need to drastically reduce its consumption of animal foods, and probably also farm more intensively-meaning fewer green fields, and more factory-style production.But switching to a mainly plant-based diet wouldn’t help. There is a good reason why the UK is dominated by animal husbandry: most of its terrain doesn’t have the right soil or climate to grow crops on a commercial basis. Just 25 per cent of the country’s land is suitable for crop-growing, most of which is already occupied by arable fields. Even if we converted all the suitable land to fields of fruit and veg-which would involve taking out all the nature reserves and removing thousands of people from their homes-we would achieve only a 30 per cent boost in crop production.Just 23 per cent of the fruit and vegetables consumed in the UK are currently home-grown, so even with the most extreme measures we could meet only 30 per cent of our fresh produce needs. That is before we look for the space to grow the grains, sugars, seeds and oils that provide us with the vast bulk of our current calorie intake.1. Some people argue that food self-sufficient in UK would ___.2. The report by the University of Leeds shows that in the UK _.3. Crop-growing in the UK is restricted due to _.4. It can be learned from the last paragraph that British people _.5. The author’s attitude to food self-sufficient in the UK is ___.

“Reskilling” is something that sounds like a buzzword but is actually a requirement if we plan to have a future where a lot of would-be workers do not get left behind. We know we are moving into a period where the jobs in demand will change rapidly, as will the requirements of the jobs that remain. Research by the World Economic Forum finds that on average 42 per cent of the “core skills” within job roles will change by 2022. That is a very short timeline.The question of who should pay for reskilling is a thorny one. For individual companies, the temptation is always to let go of workers whose skills are no longer in demand and replace them with those whose skills are. That does not always happen. AT&T is often given as the gold standard of a company that decided to do a massive reskilling program rather than go with a fire-and-hire strategy. Other companies had also pledged to create their own plans. When the skills mismatch is in the broader economy, though, the focus usually turns to government to handle. Efforts in Canada and elsewhere have been arguably languid at best, and have given us a situation where we frequently hear of employers begging for workers, even at times and in regions where unemployment is high.With the pandemic, unemployment is very high indeed. In February, at 3.5 per cent and 5.5 per cent respectively, unemployment rates in Canada and United States were at generational lows and worker shortages were everywhere. As of May, those rates had spiked up to 13.3 per cent and 13.7 per cent, and although many worker shortages had disappeared, not all had done so. In the medical field, to take an obvious example, the pandemic meant that there were still clear shortages of doctors, nurses and other medical personnel.Of course, it is not like you can take an unemployed waiter and train him to be a doctor in a few weeks. But even if you cannot close that gap, maybe you can close others, and doing so would be to the benefit of all concerned. That seems to be the case in Sweden: When forced to furlough 90 per cent of their cabin staff, Scandinavian Airlines decided to start up a short retraining program that reskilled the laid-off workers to support hospital staff. The effort was a collective one and involved other companies as well as a Swedish university.1. Research by the World Economic Forum suggests ___.2. AT&T is cited to show _.3. Efforts to resolve the skills mismatch in Canada _.4. We can learn from Paragraph 3 that there was _.5. Scandinavian Airlines decided to ___.

(10 points)Net-zero rules set to send cost of new homes and extensions soaringNew building regulations aimed at improving energy efficiency are set to increase the price of new homes, as well as those of extensions and loft conversions on existing ones.The rules, which came into effect on Wednesday in England, are part of government plans to reduce the UK’s carbon emissions to net zero by 2050. They set new standards for ventilation, energy efficiency and heating, and state that new residential buildings must have charging points for electric vehicles.The moves are the most significant change to building regulations in years, and industry experts say they will inevitably lead to higher prices at a time when a shortage of materials and high labour costs are already driving up bills.Brian Berry, chief executive of the Federation of Master Builders, a trade group for small and medium-sized builders, says the measures will require new materials, testing methods, products and systems to be installed. “All this comes at an increased cost during a time when prices are already sky high. Inevitably, consumers will have to pay more,” he says.Gareth Belsham, of surveyors Naismiths, says “people who are upgrading, or extending their home, will be directly affected. The biggest changes relate to heating and insulation,” he says. “There are new rules concerning the amount of glazing used in extensions, and any new windows or doors must be highly insulated.”Windows and doors will have to adhere to higher standards, while there are new limits on the amount of glazing you can have to reduce unwanted heat from the sun.Thomas Goodman, of My Job Quote, a site which sources quotes, says this will bring in new restrictions for extensions. “Glazing on windows, doors and roof lights must cover no more than 25% of the floor area to prevent heat loss,” he says.As the rules came into effect last Wednesday, property developers were rushing to file plans just before the deadline, according to Belsham. Any plans submitted before that date are considered to be under the previous rules, and can go ahead as long as work starts before 15 June next year.Builders which have costed projects, but have not filed the paperwork, may need to go back and submit fresh estimates, says Marcus Jefford of Build Aviator, which prices projects.Materials prices are already up 25% in the last two years, according to figures from the Construction Products Association. How much overall prices will increase as a result of the rule changes is not clear. “While admirable in their intentions, they will add to the cost of housebuilding at a time when many already feel that they are priced out of homeownership,” says Jonathan Rolande of the National Association of Property Buyers. “An average extension will probably see around £3,000 additional cost thanks to the new regs.”John Kelly, a construction lawyer at Freeths law firm, believes prices will eventually come down. But not in the immediate future. “As the marketplace adapts to the new requirements, and the technologies that support them, the scaling up of these technologies will eventually bring costs down, but in the short term, we will all have to pay the price of the necessary transition.” he says.However, the long-term effects of the changes will be more comfortable and energy-efficient homes, adds Andrew Mellor. “Homeowners will probably recoup that cost over time in energy bill savings. It will obviously be very volatile at the moment, but they will have that benefit over time.”

Teenagers are paradoxical. That’s a mild and detached way of saying something that parents often express with considerably stronger language. But the paradox is scientific as well as personal. In adolescence, helpless and dependent children who have relied on grown-ups for just about everything become independent people who can take care of themselves and help each other. At the same time, once cheerful and compliant children become rebellious teenage risk-takers, often to the point of self-destruction. Accidental deaths go up dramatically in adolescence. A new study published in the journal Child Development, by Eveline Crone of the University of London and colleagues, suggests that the positive and negative sides of teenagers go hand in hand. The study is part of a new wave of thinking about adolescence. For a long time, scientists and policy makers concentrated on the idea that teenagers were a problem that needed to be solved. The new work emphasizes that adolescence is a time of opportunity as well as risk. The researchers studied “prosocial” and rebellious traits in more than 200 children and young adults, ranging from 11 to 28 years old. The participants filled out questionnaires about how often they did things that were altruistic and positive, like sacrificing their own interests to help a friend, or rebellious and negative, like getting drunk or staying out late. Other studies have shown that rebellious behavior increases as you become a teenager and then fades away as you grow older. But the new study shows that, interestingly, the same pattern holds for prosocial behavior. Teenagers were more likely than younger children or adults to report that they did things like unselfishly help a friend. Most significantly, there was a positive correlation between prosociality and rebelliousness. The teenagers who were more rebellious were also more likely to help others. The good and bad sides of adolescence seem to develop together. Is there some common factor that underlies these apparently contradictory developments? One idea is that teenage behavior is related to what researchers call “reward sensitivity”. Decision-making always involves balancing rewards and risks, benefits and costs. “Reward sensitivity” measures how much reward it takes to outweigh risk. Teenagers are particularly sensitive to social rewards—winning the game, impressing a new friend, getting that boy to notice you. Reward sensitivity, like prosocial behavior and risk-taking, seems to go up in adolescence and then down again as we age. Somehow, when you hit 30, the chance that something exciting and new will happen at that party just doesn’t seem to outweigh the effort of getting up off the couch.1. According to paragraph 1 children growing into adolescence tend to .2. It can be learned from paragraph 2 that Crone’s study .3. What does Crone’s study find about prosocial behavior?4.

The Internet may be changing merely what we remember, not our capacity to do so, suggests Columbia University psychology professor Betsy Sparrow. In 2011, Sparrow led a study in which participants were asked to record 40 factoids in a computer (“an ostrich’s eye is bigger than its brain,” for example). Half of the participants were told the information would be erased, while the other half were told it would be saved. Guess what? The latter group made no effort to recall the information when quizzed on it latter, because they knew they could find it on their computers. In the same study, a group was asked to remember both the information and the folders it was stored in. They didn’t remember the information, but they remembered how to find the folders. In other words, human memory is not deteriorating but “adapting to new communications technology,” Sparrow says.In a very practical way, the Internet is becoming an external hard drive for our memories, a process known as “cognitive offloading.” Traditionally, this role was fulfilled by data banks, libraries, and other humans. Your father may never remember birthdays because your mother does, for instance. Some worry that this is having a destructive effect on society, but Sparrow sees an upside. Perhaps, she suggests, the trend will change our approach to learning from a focus on individual facts and memorization to an emphasis on more conceptual thinking—something that is not available on the Internet. “I personally have never seen all that much intellectual value in memorizing things,” Sparrow says, adding that we haven’t lost our ability to do it.Still other experts say it’s too soon to understand how the Internet affects our brains. There is no experimental evidence showing that it interferes with our ability to focus, for instance, wrote psychologists Christopher Chabris and Daniel Simons. And surfing the web exercised the brain more than reading did among computer-savvy older adults in a 2008 study involving 24 participants at the Semel Institute for Neuroscience and Human Behavior at the University of California, Los Angels.“There may be costs associated with our increased reliance on the Internet, but I’d have to imagine that the overall benefits are going to outweigh those costs,” observes psychology professor Benjamin Storm. “It seems pretty clear that memory is changing, but is it changing for the better? At this point, we don’t know.”1. Sparrow’s study shows that with the Internet, the human brain will .2. The process of “cognitive offloading” .3.

It’s easy to dismiss as absurd the federal government’s ideas for plugging the chronic funding gap of our national parks. Can anyone really think it’s a good idea to allow Amazon deliveries to your tent in Yosemite or food trucks to line up under the redwood trees at Sequoia National Park? But the administration is right about one thing: U.S. national parks are in crisis. Collectively, they have a maintenance backlog of more than $12 billion. Roads, trails, restrooms, visitor centers and other infrastructure are crumbling. But privatizing and commercializing the campgrounds would not be the panacea that the Interior Department’s Outdoor Advisory Committee would have us believe. Campgrounds are a tiny portion of the overall infrastructure backlog, and concessionaires in the parks hand over, on average, only about 5% of their revenues to the National Park Service. Moreover, increased privatization would certainly undercut one of the major reasons why 300 million visitors come to the parks each year: to enjoy nature and get a respite from the commercial drumbeat that overwhelms daily life. The real problem is that the parks have been chronically starved of funding. We conducted a comprehensive survey examining how U.S. residents view their national parks, and we found that Americans place a very high value on them—whether or not they actually visit them. The peer-reviewed economic survey of 700 U.S. taxpayers, conducted by mail and internet, also found that people would be willing to pay a significant amount of money to make sure the parks and their programs are kept intact. Some 81% of respondents said they would be willing to pay additional taxes for the next 10 years to avoid any cuts to the national parks. The national parks provide great value to U.S. residents both as places to escape and as symbols of nature. On top of this, they produce value from their extensive educational programs, their positive impact on the climate through carbon sequestration, their contribution to our cultural and artistic life, and of course through tourism. The parks also help keep America’s past alive, working with thousands of local jurisdictions around the country to protect historical sites—including Ellis Island and Gettysburg—and to bring the stories of these places to life. The parks do all this on a shoestring. Congress allocates only $3 billion a year to the national park system—an amount that has been flat since 2001 (in inflation-adjusted dollars) with the exception of a onetime boost in 2009 as part of the Obama stimulus package. Meanwhile, the number of annual visitors has increased by more than 50% since 1980, and now stands at 330 million visitors per year.1. What problem are U.S. national parks faced with .2.

In the quest for the perfect lawn, homeowners across the country are taking a shortcut—and it is the environment that is paying the price. About eight million square metres of plastic grass is sold each year but opposition has now spread to the highest gardening circles. The Chelsea Flower Show has banned fake grass from this year’s event, declaring it to be not part of its ethos. The Royal Horticultural Society (RHS), which runs the annual show in west London, says it has introduced the ban because of the damage plastic grass does to the environment and biodiversity. Ed Horne, of the RHS, said: “We launched our sustainability strategy last year and fake grass is just not in line with our ethos and views on plastic. We recommend using real grass because of its environmental benefits, which include supporting wildlife alleviating flooding and cooling the environment.” The RHS’s decision comes as campaigners try to raise awareness of the problems fake grass causes. A Twitter account, which claims to “cut through the greenwash” of artificial grass, already has more than 20,000 followers. It is trying to encourage people to sign two petitions, one calling for a ban on the sale of plastic grass and another calling for an “ecological damage” tax on such lawns. They have gathered 7,276 and 11,282 signatures. However, supporters of fake grass point out that there is also an environmental impact with natural lawns, which need mowing and therefore usually consume electricity or petrol. The industry also points out that real grass requires considerable amounts of water, weed killer or other treatments and that people who lay fake grass tend to use their garden more. The industry also claims that people who lay fake grass spend an average of £500 on trees or shrubs for their garden, which provides habitat for insects. In response to another petition last year about banning fake lawns, which gathered 30,000 signatures, the government responded that it has “no plans to ban the use of artificial grass”. It added: “We prefer to help people and organizations make the right choice rather than legislating on such matters. However, the use of artificial grass must comply with the legal and policy safeguards in place to protect biodiversity and ensure sustainable drainage, while measures such as the strengthened biodiversity duty should serve to encourage public authorities to consider sustainable alternatives.”1.

In the late 18th century, William Wordsworth became famous for his poems about nature. And he was one of the founders of a movement called Romanticism, which celebrated the wonders of the natural world. Poetry is powerful. Its energy and rhythm can capture a reader, transport them to another world and make them see things differently. Through carefully selected words and phrases, poems can be dramatic, funny, beautiful, moving and inspiring. No one knows for sure when poetry began but it has been around for thousands of years, even before people could write. It was a way to tell stories and pass down history. It is closely related to song and even when written it is usually created to be performed out loud. Poems really come to life when they are recited. This can also help with understanding them too, because the rhythm and sounds of the words become clearer.

Although we try our best, sometimes our paintings rarely turn out as originally planned. Changes in the light, the limitations of your painting materials and the lack of experience and technique mean that what you start out trying to achieve may not come to life the way that you expected. Although this can be frustrating and disappointing, it turns out that this can actually be good for you. Unexpected results have two benefits: you pretty quickly learn to deal with disappointment and realise that when one door closes, another opens. You also quickly learn to adapt and come up with creative solutions to the problems the painting presents and thinking outside the box will become your second nature. In fact, creative problem-solving skills are incredibly useful in daily life, with which you’re more likely to be able to find a solution when problem arises.

How to Get Active Again After a BreakMoving your body has been shown to reduce anxiety and depression, lower rates of many types of cancer and the risk of a heart ¬attack, and improve overall immunity. It also helps build strength and stamina. Getting back into exercise can be a challenge in the best of times, but with gyms and in-person exercise classes off-limits to many people these days because of COVID-19 concerns, it can be tricky to know where to start. And it’s important to get the right dose of activity. “Too much too soon either results in injury or burnout,” says Mary Yoke, PhD, a faculty member in the kinesiology department at Indiana University in Bloomington.The following simple strategies will help you return to exercise safely after a break.1. Don’t try to go back to what you were doing before your break. If you were walking 3 miles a day, playing 18 holes of golf three times week, or lifting 10-pound dumbbells for three sets of 10 reps, reduce activity to half a mile every other day, or nine holes of golf once a week with short walks on other days, or use 5-pound dumbbells for one set of 10 reps.Increase time, distance, and intensity gradually. “This isn’t something you can do overnight,” Denay says. But you will reap benefits such as less anxiety and improved sleep right away.2. If you’re breathing too hard to talk in complete sentences, back off. If you feel good, go a little longer or faster. Feeling wiped out after a session? Go easier next time. And stay alert to serious symptoms, such as chest pain or pressure, severe shortness of breath or dizziness, or faintness, and seek medical attention immediately.3. Consistency is the key to getting stronger and building endurance and stamina.Ten minutes of activity per day is a good start, says Marcus Jackovitz, DPT, a physical therapist at the University of Miami Hospital. All the experts we spoke with highly recommend walking because it’s the easiest, most accessible form of exercise. Although it can be a workout on its own, if your goal is to get back to Zumba classes, tennis, cycling, or any other activity, walking is also a great first step.4. Even if you can’t yet do a favorite activity, you can practice the moves. With or without a club or racket, swing like you’re hitting the ball. Paddle like you're in a kayak or canoe. Mimic your favorite swimming strokes. The action will remind you of the joy the activity brought you and prime your muscles for when you can get out there again.5. Exercising with others “can keep you accountable and make it more fun, so you're more likely to do it again,” Jackovitz says.You can do activities such as golf and tennis or take a walk with others and still be socially distant. But when you can’t connect in person, consider using technology. Chat on the phone with a friend while you walk around your neighborhood. FaceTime or Zoom with a relative as you strength train or stretch at home.You can also join a livestream or on-demand exercise class. SilverSneakers offers them for older adults, or try EverWalk for virtual challenges.

Although ethics classes are common around the world, scientists are unsure if their lessons can actually change behavior; evidence either way is weak, relying on contrived laboratory tests or sometimes unreliable self-reports. But a new study published in Cognition found that, in at least one real-world situation, a single ethics lesson may have had lasting effects.The researchers investigated one class session’s impact on eating meat. They chose this particular behavior for three reasons, according to study co-author Eric Schwitzgebel, a philosopher at the University of California, Riverside: students’ attitudes on the topic are variable and unstable, behavior is easily measurable, and ethics literature largely agrees that eating less meat is good because it reduces environmental harm and animal suffering. Half of the students in four large philosophy classes read an article on the ethics of factory-farmed meat, optionally watched an 11-minute video on the topic and joined a 50-minute discussion. The other half focused on charitable giving instead. Then, unknown to the students, the researchers studied their anonymized meal-card purchases for that semester—nearly 14,000 receipts for almost 500 students.Schwitzgebel predicted the intervention would have no effect; he had previously found that ethics professors do not differ from other professors on a range of behaviors, including voting rates, blood donation and returning library books. But among student subjects who discussed meat ethics, meal purchases containing meat decreased from 52 to 45 percent—and this effect held steady for the study’s duration of several weeks. Purchases from the other group remained at 52 percent.“That's actually a pretty large effect for a pretty small intervention,” Schwitzgebel says.Psychologist Nina Strohminger at the University of Pennsylvania, who was not involved in the study, says she wants the effect to be real but cannot rule out some unknown confounding variable. And if real, she notes, it might be reversible by another nudge: “Easy come, easy go.”Schwitzgebel suspects the greatest impact came from social influence—classmates or teaching assistants leading the discussions may have shared their own vegetarianism, showing it as achievable or more common. Second, the video may have had an emotional impact. Least rousing, he thinks, was rational argument, although his co-authors say reason might play a bigger role. Now the researchers are probing the specific effects of teaching style, teaching assistants’ eating habits and students’ video exposure. Meanwhile Schwitzgebel—who had predicted no effect—will be eating his words.1. Scientists generally believe that the effects of ethics classes are .2. Which of the following is a reason for the researchers to study meat-eating?3. Eric Schwitzgebel’s previous findings suggest that ethics professors .4.

We have all encountered them, in both our personal and professional lives. Think about the times you felt tricked or frustrated by a membership or subscription that had a seamless sign-up process but was later difficult to cancel. Something that should be simple and transparent can be complicated, intentionally or unintentionally, in ways that impair consumer choice. These are examples of dark patterns.First coined in 2010 by user experience expert Harry Brignull, “dark patterns” is a catch-all term for practices that manipulate user interfaces to influence the decision-making ability of users. Brignull identifies 12 types of common dark patterns, ranging from misdirection and hidden costs to “roach motel”, where a user experience seems easy and intuitive at the start, but turns difficult when the user tries to get out.In a 2019 study of 53,000 product pages and 11,000 websites, researchers found that about one in 10 employs these design practices. Though widely prevalent, the concept of dark patterns is still not well understood. Business and nonprofit leaders should be aware of dark patterns and try to avoid the gray areas they engender.Where is the line between ethical, persuasive design and dark patterns? Businesses should engage in conversations with IT, compliance, risk, and legal teams to review their privacy policy, and include in the discussion the customer/user experience designers and coders responsible for the company’s user interface, as well as the marketers and advertisers responsible for sign-ups, checkout baskets, pricing, and promotions. Any or all these teams can play a role in creating or avoiding “digital deception.”Lawmakers and regulators are slowly starting to address the ambiguity around dark patterns, most recently at the state level. In March, the California Attorney General announced the approval of additional regulations under the California Consumer Privacy Act (CCPA) that “ensure that consumers will not be confused or misled when seeking to exercise their data privacy rights.” The regulations aim to ban dark patterns—this means prohibiting companies from using “confusing language or unnecessary steps such as forcing them to click through multiple screens or listen to reasons why they shouldn’t opt out.”As more states consider promulgating additional regulations, there is a need for greater accountability from within the business community. Dark patterns also can be addressed on a self-regulatory basis, but only if organizations hold themselves accountable, not just to legal requirements, but also to industry best practices and standard.1.

More Americans are opting to work well into retirement, a growing trend that threatens to up end the old workforce model.One in three Americans who are at least 40 have or plan to have a job in retirement to prepare for a longer life, according to a survey conducted by Harris Poll for TD Ameritrade. Even more surprising is that more than half of “unretirees”—those who plan to work in retirement or went back to work after retiring—said they would be employed in their later years even if they had enough money to settle down, the survey showed.Financial needs aren’t the only culprit for the “unretirement” trend. Other reasons, according to the study, include personal fulfillment such as staying mentally fit, preventing boredom or avoiding depression.“The concept of retirement is evolving,” said Christine Russell, senior manager of retirement at TD Ameritrade. “It’s not just about finances. The value of work is also driving folks to continue working past retirement.”One reason for the change in retirement patterns: Americans are living longer. The share of the population 65 and older was 16% in 2018, up 3.2% from the prior year, according to the U.S. Census Bureau. That’s also up 30.2% since 2010.Because of longer life spans, Americans are also boosting their savings to preserve their nest eggs, the TD Ameritrade study showed, which surveyed 2,000 adults between 40 to 79. Six in 10 “unretirees” are increasing their savings in anticipation of a longer life, according to the survey. Among the most popular ways they are doing this, the company said, is by reducing their overall expenses, securing life insurance or maximizing their contributions to retirement accounts.Unfortunately, many people who are opting to work in retirement are preparing to do so because they are worried about making ends meet in their later years, said Brent Weiss, a co-founder at Baltimore-based financial-planning firm Facet Wealth. He suggested that preretirees should speak with a financial adviser to set long-term financial goals.“The most challenging moments in life are getting married, starting a family and ultimately retiring,” Weiss said. “It’s not just a financial decision, but an emotional one. Many people believe they can’t retire.”1. The survey conducted by Harris Poll indicates that .2. It can be inferred from Paragraph 3 that Americans tend to think that .3.

On a recent sunny day, 13,000 chickens roam over Larry Brown’s 40 windswept acres in Shiner, Texas. Some rest in the shade of a parked car. Others drink water with the cows. This all seems random, but it’s by design, part of what the $6.1 billion U.S. egg industry bets will be its next big thing: climate-friendly eggs.These eggs, which are making their debut now on shelves for as much as $8 a dozen, are still labeled organic and animal-friendly, but they’re also from birds that live on farms using regenerative agriculture—special techniques to cultivate rich soils that can trap greenhouse gases. Such eggs could be marketed as helping to fight climate change.“I’m excited about our progress,” says Brown, who harvests eggs for Denver-based NestFresh Eggs and is adding more cover crops that draw worms and crickets for the chickens to eat. The birds’ waste then fertilizes fields. Such improvements “allow our hens to forage for higher-quality natural feed that will be good for the land, the hens, and the eggs that we supply to our customers.”The egg industry’s push is the first major test of whether animal products from regenerative farms can become the next premium offering. In barely more than a decade, organic eggs went from being dismissed as a niche product in natural foods stores to being sold at Walmart. More recently there were similar doubts about probiotics and plant-based meats, but both have exploded into major supermarket categories. If the sustainable-egg rollout is successful, it could open the floodgates for regenerative beef, broccoli, and beyond.Regenerative products could be a hard sell, because the concept is tough to define quickly, says Julie Stanton, associate professor of agricultural economics at Pennsylvania State University Brandywine. Such farming also brings minimal, if any, improvement to the food products (though some producers say their eggs have more protein).The industry is betting that the same consumers paying more for premium attributes such as free-range, non-GMO, and pasture-raised eggs will embrace sustainability. Surveys show that younger generations are more concerned about climate change, and some of the success of plant-based meat can be chalked up to shoppers wanting to signal their desire to protect the environment. Young adults “really care about the planet,” says John Brunnquell, president of Egg Innovations. “They are absolutely altering the food chain beyond what I think even they understand what they’re doing.”1.
