6 . Take the Money and Run

A Latin phrase beloved by every old-fashioned British schoolmaster was mens sana in corpore sano—a healthy mind in a healthy body. Greater physical activity is associated with better mental, as well as physical health. And it might also be linked to greater worker productivity, and thus faster economic growth. That is the conclusion of a new report from a European think tank—RAND.

The RAND study looks at different measures: absenteeism(when workers take time off for illness)and presenteeism(when they turn up for work but are less productive because of sickness). The latter measure was self-reported by employees, who were asked whether their work was negatively affected by health issues. The survey suggests that between 3 and 4.5 working days each year are lost as a consequence of workers being physically inactive. This is between 1.3% and 2% of annual working time. Most of this was down to presenteeism.

Another potential gain from improved fitness is reduced health-care costs. In America, where health care is often provided through employment-based systems, firms could benefit. RAND estimates that total American health savings could be $ 6 billion a year by 2025. But the study's authors conclude that if people met certain exercise targets, global GDP could be around 0.17-0.24% higher by 2050. Nothing to laugh at in a world of slowing growth.

How to encourage workers to become more active? Rewards are useful but only if they have conditions: giving all employees free gym membership does not seem to work. Another RAND Europe study examined an experiment in which workers were each given an Apple watch, payable in installment (分期付款)at a discounted price—but only to those who agreed to have their physical activity monitored. Monthly repayments depended on how much exercise they took.

If they met the targets they ended up paying 10% of the watch's list price; those who took no exercise paid the full price. This approach takes advantage of a fact that people are eager to avoid paying more. On average, those participating in the scheme undertook 30% more exercise than before.

The problem is that many people are too optimistic about their health, ignoring the risks they face. This means that participation in workplace exercise plans tends to be low, around 7% in the sample studied by RAND. Firms are not the only ones that can encourage a healthier lifestyle; friends and families are likely to be more important. But businesses can play a bigger role.

If RAND is right, this may bring them financial benefits. Company taskmasters may yet grow fond of an adapted saying: mens sana in corporate sano.

Nowadays, millions of people log onto TikTok (Dou Yin in Chinese) to watch something    1     (call) Mukbang (Chibo in Chinese). It might seem strange,     2       these videos are surprisingly satisfying to watch. It     3       (allow) people to “eat” with others even though they are at home alone. However, there is a dark side to Mukbang. The way people eat food in most of these videos isn’t healthy. Some Mukbangers eat too much food and it makes their audience uncomfortable. This could encourage bad habits    4     might lead to serious eating problems.

8 . Alida Monaco doesn’t spend her summers doing the usual teenage work, like working at the mall. Instead，she ‘ s studying.

It used to be that a summer job was considered a teenage thing. Today, Monaco ,who has never had a summer job, is part of growing trend (趋势)teenagers focusing on their studies, even during the summer. That’s down from 72% of Americans aged 16 to 19 who worked in July of 1978, according to the U. S. Bureau of Labor Statistics.

Fierce (激烈的)competition, older workers returning to the workforce and weak economic growth are all adding to the decrease of teenagers in the workforce. But as schoolwork grows increasingly heavy and homework eats up more time, data suggest the biggest reason why some teens won’t be working this summer is that they simply don’t1 have time.

For college - bound teens, some teachers even advise students not to waste time on a summer job. “ Some of my students only have about six weeks off in the summer,” said Shannon Reed, a lecturer at the University of Pittsburgh and a former high school English teacher.” I could never advise that they get jobs during that short break. ”

Young people who don’t work may miss out on valuable skills that they’11 need control and help people learn to deal with adult situations. But Monaco, who plans to attend Harvard, isn’t fazed by her lack(缺乏)of work experience. “Maybe I have missed out on a couple of life skills, “she said. “ But I don’t think it will harm me in way .”

Living off grid

When you need electricity, you just plug in the machine and switch it on. If you need water, you turn on the tap.     1     For many people, these facilities are the basics of civilized society and the idea of living without them seems risky. Yet for a growing number of people, the idea of living off grid — without electricity, water or sewage — is an increasingly attractive lifestyle.

Off-gridders do not have to give up electricity or a modern lifestyle — some choose to, but most use small hydroelectric power systems, solar panels or windmills to generate enough power for their needs. Heating and cooking needs are met by solar energy or wood burning systems, and toilet facilities range from non-water toilets to outside compost toilets.     2     It ranges from traditional yurts (a type of tent) to luxury house with high-speed internet and central heating. Whether they live in simple homes or luxury houses, what they all have in common is that their lifestyles do not create any pollution or carbon emissions — the ultimate goal for off-gridders.

Around 100,000 people are thought to be living off grid in the UK now.     3     They grow their own food, home-school their children and provide their own medical care. They are people who have been priced out of the housing market or who have grown disillusioned with what modern society can offer and who decides that an alternative lifestyle isn’t a pipe dream, but a viable option.

A part from living an alternative lifestyle, cost is a big factor in choosing to live off-grid. Off-grid houses are far cheaper to build than ordinary homes since they don’t need to be connected to the electricity or water supplies and even road access is not necessary. Materials tend to be cheaper, too. Popular options include straw or old tyres and cement.

Surprisingly, the biggest problem off-gridders face is not building their homes or becoming self-sufficient but getting permission to build. Rural areas away from town are the perfect choice but these are often protected by law from construction of any kind or have building restrictions. There are now several websites dedicated to land-sharing so that the costs of buying land and getting permission can be shared, and there are increasing numbers of off-grid communities.     4     Off-gridding could soon be common all over Europe and America.

10 . Clothing rental is a hot new industry and retailers (零售商) are demanding to get on board in hopes of attracting green shopper.

But is renting fashion actually more environmentally-friendly than buying it, and if so, how much more? Journalist and author Elizabeth Cline investigated (调查) this question and concluded that it's not as sustainable as it seems.

Take shipping, for example, which has to go two ways if an item is rented — receiving and returning. Cline writes that consumer transportation has the second largest carbon footprint of our collective fashion habit after manufacturing.

She writes, ''An item ordered online and then returned can send out 20 kilograms of carbon each way, and increases up to 50 kilograms for rush shipping. By comparison, the carbon impact of a pair of jeans purchased from a physical store and washed and worn at home is 33.4 kilograms, according to a 2015 study by Levi's.''

Then there's the burden of washing, which has to happen for every item when it's returned, regardless of whether or not it was worn. For most rental services, this usually means dry cleaning, a high impact and polluting process. All the rental services that Cline looked into have replaced perchloroethylene (氯乙烯), a carcinogenic (致癌的) air pollutant, still used by 70 percent of US dry cleaners, with alternatives, although these aren't great either.

Lastly, Cline fears that rental services will increase our appetite for fast fashion, simply because it's so easily accessible. There's something called ''share washing'' that makes people waste more precisely because a product or service is shared and thus is regarded as more eco-friendly. Uber is one example of this, advertised as ''a way to share rides and limit ear ownership.'' and yet ''it has been proven to discourage walking,bicycling, and public transportation use.''

Renting clothes is still preferable to buying them cheap and throwing them in the dustbin after a few wears, but we shouldn't let the availability of these services make us too satisfied. There's an even better step — that's wearing what is already in the closet.
