More Americans are opting to work well
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
Financial needs aren’t the only culprit for “the unretirement” trend.
“The concept of retirement is evolving,” said Christine Russel, senior manager of retirement at TD Ameritrade. “It’s not just about finances. The value of work is also driving folks
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. Older Americans are also the fastest-growing segment of the U.S. workforce, and boomers are expected to live longer than previous generations. The percentage of retirement-age people in the labour force has doubled over the past three decades. About 20% of people 65 and older were in the workforce in February, up from an all-time low of 10% in January in 1985, according to money manager United Income.
Unfortunately, many people who

7 . What life will be in 2050?
It’s hard to say definitively what life will be like in 2050. However, we can make some educated guesses based on the trends that are happening now. For instance, it’s likely that technology will play an even greater role in our lives than it does now. We might have flying cars, or robots to do our household chores.
The world population is projected to reach 9.7 billion by 2050, so resources may be strained. People may live in smaller homes or even underground to conserve space and energy. We may also see drastic changes in the way we get our food. With advances in technology, it’s possible that we’ll be able to create artificial meat or grow food in laboratories.
In 2050, many aspects of our life will be very different from what they are now. People’s lives, the environment, transportation, and education all change at a new level.
There will be a lot of new jobs born to serve the development of society. And if you are good at using social media, you can be an online celebrity and make a lot of money. You can also choose to be a full-time housewife and take care of your family if you want.
Rockefeller University mathematical biologist Joel Cohen predicts that by 2050, the world will be majority urban dwellers with a high average age. In contrast, U.S. cities theorist Richard Florida believes that urbanization trends will result in a work-from-home economy and do away with divisions between home and work life. Other experts interviewed by Popular Mechanics envision a future in which solar energy is ubiquitous, 3-D printing has replaced traditional manufacturing and everyone has a personal assistant in the form of an AI.
However, there are also some reasons to be pessimistic about the future. The world will be a more dangerous place in 2050. Global warming will cause rising sea levels and extreme weather conditions that will make life difficult for people around the world.
A.As technology continues to develop, so does the concern for environment. |
B.By 2050, everyone will be able to afford higher education. |
C.In addition, there will be new diseases that we have not yet seen. |
D.In general, life in 2050 is more convenient, more comfortable and more fun. |
E.There are some grounds for optimism in this scenario. |
F.As a result, we will have a lot of health problems. |
8 . 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 high-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.”
