We talk continuously about how to make children more”resilient(有恢复力的)”，but whatever were doing, it's not working. Rates of anxiety disorders and depression are rising rapidly among teenagers. What are we doing wrong?
Nassim Taleb invented the word “antifragile” and used it to describe a small but very important class of systems that gain from shocks, challenges, and disorder. The immune system is one of them: it requires exposure to certain kinds of bacteria and potential allergens(过敏源)in childhood in order to develop to its full ability.
Children’s social and emotional abilities are as antifragile as their immune systems. If we overprotect kids and keep them “safe” from unpleasant social situations and negative emotions we deprive(剥夺)them of the challenges and opportunities for skill-building they need to grow strong. Such children are likely to suffer more when exposed later to other unpleasant but ordinary life events, such as teasing and social rejection
It's not the kids fault. In the UK, as in the US, parents became much more fearful in the 1980s and 1990s as cable TV and later the Internet exposed everyone, more and more, to those rare occurrences of crimes and accidents that now occur less and less, Outdoor play and independent mobility went down; screen time and adult-monitored activities went up.
Yet free play in which kids work out their own rules of engagement, take small risks, and learn to master small dangers turns out to be vital for the development of adult social and even physical competence, Depriving them of free play prevents their social-emotional growth. Norwegian play researchers Ellen Sandseter and Leif Kennair warned: “We may observe an increased anxiety or mental disorders in society if children are forbidden from participating in age adequate risky play.”
They wrote those words in 2011. Over the following few years, their prediction came true. Kids born after 1994 are suffering from much higher rates of anxiety disorders and depression than the previous generation did. Besides, there is also a rise in the rate at which teenage girls are admitted to hospital for deliberately harming themselves.
What can we do to change these trends? How can we raise kids strong enough to handle the ordinary and extraordinary challenges of life? We can’t guarantee that giving primary school children more independence today will bring down the rate of teenage suicide tomorrow. The links between childhood overprotection and teenage mental illness are suggestive but not clear-cut. Yet there are good reasons to suspect that by depriving our naturally antifragile kids of the wide range of experiences they need to become strong, we are systematically preventing their growth. We should let go-and let them grow.

The morning had been a disaster. My tooth was aching, and I’d been in an argument with a friend. Her words still hurt: “The trouble with you is that you won’t put yourself in my place. Can’t you see things from my point of view?”I shook my head stubbornly--and felt the ache in my tooth. I’d thought I could hold out till my dentist came back from holiday, but the pain was really unbearable. I started calling the dentists in the phone book, but no one could see me immediately. Finally, at about lunch time, I got lucky.
“If you come by right now,” the receptionist said, “the dentist will fit you in.”
I took my purse and keys and rushed to my car. But suddenly I began to doubt about the dentist. What kind of dentist would be so eager to treat someone at such short notice? Why wasn’t he as busy as the others?
In the dentist’s office, I sat down and looked around. I saw nothing but the bare walls and I became even more worried. The assistant noticed my nervousness and placed her warm hand over my ice-cold one.
When I told her my fears, she laughed and said, “Don’t worry. The dentist is very good.”
“How long do I have o wait for him?”I asked impatiently.
“Come on, he is coming. Just lie down and relax. And enjoy the artwork,” the assistant said.
“The artwork?” I was puzzled.
The chair went back, suddenly I smiled. There was a beautiful picture, right where I could enjoy it :on the ceiling. How considerate the dentist was! At that moment, I began to understand what my friend meant by her words.
What a relief!

Plastic-Eating Worms
Humans produce more than 300 million tons of plastic every year. Almost half of that winds up in landfills(垃圾填埋场), and up to 12 million tons pollute the oceans. So far there is no effective way to get rid of it, but a new study suggests an answer may lie in the stomachs of some hungry worms.
Researchers in Spain and England recently found that the worms of the greater wax moth can break down polyethylene, which accounts for 40% of plastics. The team left 100 wax worms on a commercial polyethylene shopping bag for 12 hours, and the worms consumed and broke down about 92 milligrams, or almost 3% of it. To confirm that the worms’ chewing alone was not responsible for the polyethylene breakdown, the researchers made some worms into paste(糊状物) and applied it to plastic films. 14 hours later the films had lost 13% of their mass — apparently broken down by enzymes (酶) from the worms’ stomachs. Their findings were published in Current Biology in 2017.
Federica Bertocchini, co-author of the study, says the worms’ ability to break down their everyday food — beeswax — also allows them to break down plastic. ＂Wax is a complex mixture, but the basic bond in polyethylene, the carbon-carbon bond, is there as well, ＂she explains, ＂The wax worm evolved a method or system to break this bond. ＂
Jennifer DeBruyn, a microbiologist at the University of Tennessee, who was not involved in the study, says it is not surprising that such worms can break down polyethylene. But compared with previous studies, she finds the speed of breaking down in this one exciting. The next step, DeBruyn says, will be to identify the cause of the breakdown. Is it an enzyme produced by the worm itself or by its gut microbes(肠道微生物)?
Bertocchini agrees and hopes her team’s findings might one day help employ the enzyme to break down plastics in landfills. But she expects using the chemical in some kind of industrial process — not simply ＂millions of worms thrown on top of the plastic.＂
