What Theresa Loe is doing proves that a large farm isn't a prerequisite for a modern grow-your-own lifestyle. On a mere 1/10 of an acre in Los Angeles, Loe and her family grow, can (装罐) and preserve much of the food they consume.

    Loe is a master food preserver, gardener and canning expert. She also operates a website, where she shares her tips and recipes, with the goal of demonstrating that everyone has the ability to control what's on their plate.

    Loe initially went to school to become an engineer, but she quickly learned that her enthusiasm was mainly about growing and preparing her own food. “ got into cooking my own food and started growing my own herbs(香草)and foods for that fresh flavor,” she said. Engineer by day, Loe learned cooking at night school. She ultimately purchased a small piece of land with her husband and began growing their own foods.

    “I teach people how to live farm-fresh without a farm,” Loe said. Through her website Loe emphasizes that ''anybody can do this anywhere.” Got an apartment with a balcony (阳台)? Plant some herbs. A window? Perfect spot for growing. Start with herbs, she recommends, because “they're very forgiving.” Just a little of the herbs “can take your regular cooking to a whole new level,” she added. “I think it's a great place to start.” Then? Try growing something from a seed, she said, like a tomato or some tea.

    Canning is a natural extension of the planting she does. With every planted food, Loe noted, there's a moment when it's bursting with its absolute peak flavor. “I try and keep it in a time capsule in a canning jar,” Loe said. “Canning for me is about knowing what's in your food, knowing where it comes from.”

    In addition to being more in touch with the food she's eating, another joy comes from passing this knowledge and this desire for good food to her children: “Influencing them and telling them your opinion on not only being careful what we eat but understanding the bigger picture,” she said, “that if we don't take care of the earth, no one will.”

    I sit on the stoop (门廊) in front of my friend's house at the top of a steep hill. And now my friend is late, and I'm stuck here waiting.

    I see a man approaching.

    "Por favor. Call 911," the man says. "Finger. Cut." With his left hand, he is pressing the handkerchief around his right little finger.

    "No. Have. Phone," I say, as if English is also my second language.

    "Have phone," he says, and dips his chin toward his front pants pocket. There, I find a phone, and call 911.

    The operator answers, and I say "I'm with this guy, and he cut his finger."

    "Did he cut it off?"

    "Did you cut it off?"

    "Sí." He sighs.

    "Yes. He cut it off."

    "Where is it?" the operator asks.

    "Where is it?"

    "Upstairs," he says, pointing with his elbow to the house next door.

    "Go get it," she instructs me.

    I follow the man toward the house. Inside, I see a table saw(锯), and the blood spreading across the ceiling, but I don't see the finger. I lift up each foot and look underneath to be sure I've not stepped on it. I'm getting that jumpy, tight-shouldered feeling like when you've lost sight of a spider that was on your ceiling a moment ago.

    "Do you see it?" I ask him.

    He points at his own finger beside the table saw. I grab a paper towel, pinching it carefully, the way you might pick up a harmless but frightening insect.

    "We have secured the finger," I tell the operator.

    "Hang tight. The ambulance is on its way."

    We sit on the stoop waiting for the ambulance.

    "You're going to be OK," I say, putting my free hand on his sawdust-covered back.

    "Gracias," he says.

    "De nada. Esta no problemo," I reply in broken Spanish.

    It feels good to be able to comfort someone, anyone. For months now, the second my hands would go idle(闲散的), a familiar depression would climb on my back. I have been trying to put on a good face for my kid, but I feel as if I've been failing. Could I save myself? I wouldn't know how. But I am determined to save this man.

    Finally the ambulance arrives, picks him up, and they're off.

    Throughout the evening, I can't stop worrying about the man. I decide to call the hospital.

    "Hi! I helped a guy who cut off his finger, and I don't even know his name, but I'm wondering whether he came to your hospital."

    The nurse says, "His name is Jose Ramos, and he's waiting for surgery. Would you like to leave a message?"

    "No. I don't want to bother him. I just wanted to be sure he was OK."

    The next morning, I call the hospital again. This time, I'm put through to Jose's room. "How was the surgery?"

    "No surgery," he says. "No enough blood."

    "Oh, I'm sorry," I say.

    Later that day, I remember that old proverb about how if you save someone's life, you are responsible for them for the rest of their life, which never made sense to me before. Shouldn't the person who got saved owe a debt, and not the other way around? But today, I get it. It's a great honor to help someone in need.

    I start keeping a lookout for other people in need of assistance. I help push a stalled car out of the road. I aid a disoriented cyclist when her bike gets clipped by a car. I adopt a dog. Then one day, a month or two after the finger incident, I realize I have completely forgotten to be depressed. I've been so busy playing the role of local hero that I have ignored to drag my feet and stare into space and imagine the world without me.

    Now, more than a decade has passed since Jose's accident. Occasionally I search for "Jose" plus "Ramos" plus "finger." I wish I could see him again, to see how he's getting on. But more important, to thank him, because when he lost his finger, he saved my life.

    I'll be the first to admit that I am a technophobe(对技术有恐惧感的人). Who would have guessed that a website would help repay a 20-year-old loan?

    I'll always remember my last day at school. My best friend, Jenny, had organized a party in the Sixth Form Common Room.

    Jenny asked me to go to the supermarket with her to buy all the snacks. "I'm really looking forward to this party, Stingy," she said. Everyone called me Stingy instead of Debbie because they thought I didn't like to spend money. Actually, it was true.

    "There's lots of money in the kitty. Let's go crazy!" Going crazy meant buying enough snacks to feed an army. It came to ￡19.90, which was a lot of money in 1982.

    Jenny gave me a guilty(内疚的) look. "I've left-the kitty money in the common room. Can you pay and I'll give you back the money?"

    "Sure," I replied, trying to look relaxed. "Neither a lender or a borrower be" was my motto(座右铭) but I didn't want to look stingy. I gave ￡20 to the impatient shop assistant.

    Well, the Party was a great success. So great that I completely forgot about my loan until I was flying to America the next day.  I was going to live with my uncle's family until I started university.

    I tried to get in touch with Jenny but her family had moved. My ￡20 was lost. Until...

    I'd heard about a website called Friends Reunited which helped people contact old school friends.  My husband helped me log on and find my school. There she was, Jenny Frost.

    I'm now married with a beautiful daughter called Debbie. Does anyone know how to get in touch with Debbie "Stingy" Jones? I still owe her ￡20!

    We met two months later and the ￡20 was returned, plus interest(利息) of course. After all, I'm a bank manager now, so loans are my business.

    Have you ever looked out of the window of a passenger plane from 30,000 feet at the vast expanses of empty ocean and uninhabited land, and wondered how people can have any major effect on the Earth? I have. It is now becoming pretty clear that we are causing a great deal of damage to the natural environment. And the planes which rush us in comfort to destinations around the globe, contribute to one of the biggest environmental problems that we face today— global warming.

    As usual, people in the developing world are having to deal with problems created mainly by those of us in developed countries. Beatrice Schell, a spokeswoman for the European Federation for Transport and Environment says that, "One person flying in an airplane for one hour is responsible for the same greenhouse gas emissions（排放）as a typical Bangladeshi in a whole year." And every year jet aircraft produce almost as much carbon dioxide as the entire African continent does.

    There is a way of offsetting(抵消) the carbon dioxide we produce when we travel by plane. A company called Future Forests offers a service which can relieve the guilty consciences of air travelers. The Future Forest website calculates the amount of CO₂ you are responsible for producing on your flight, and for a small fee will plant a number of trees which will absorb this CO₂.

    Yesterday I returned to Japan from England, and was happy to pay Future Forests 25 pounds to plant the 3 trees which balance my share of the CO₂ produced by my return flight. Now the only thing making me lose sleep is jet lag.

    Depression(抑郁) can be a destructive illness, plaguing millions of people worldwide with feelings of sadness, hopelessness, and fatigue. Despite numerous antidepressant drugs, as many as a third of patients don't respond to medication. This has forced doctors to be more creative in finding different treatments for the condition.

    In the past two decades, researchers have tied depression to a seemingly unrelated condition: inflammation(炎症), the body's natural response to stress. It could rise from injury or inflection, or even emotional issues like an unhappy marriage or problems at work. Some amount of inflammation is generally beneficial, as it increases production of cytokines(致癌因子)，proteins that help us heal and protect us from the effects of overwork.

    But excessive cytokine levels, and the inflammation they bring on, could come at a cost—a number of studies suggests that high levels of cytokines could contribute to depression.

    Cytokines can reach the brain several ways: directly through the blood-brain barrier or indirectly by binding to nerve fibers elsewhere, which send signals to the brain to produce the inflammation molecules. In the brain, cytokines can disturb the production and release of several important signaling chemicals, including serotonin, dopamine and glutamate, which help control emotion, appetite, sleep, learning and memory. It's though that a lack of serotonin activity in the brain causes depression; most antidepressants increase the activity. But cytokines also have been shown to activate stress hormone signaling in the brain, which man also serve to develop depression.

    With all the evidence implicating inflammation in depression, doctors have been anxious to test anti-inflammatory drugs as a potential treatment. Four small studies published between 2006 and 2017 by research groups in Europe and Iran found that adults diagnosed with depression who took aspirin or another anti-inflammatory drug called Celecoxib, along with an antidepressant, got more relief from feelings of sadness, hopelessness, guilt and fatigue compared with those taking an antidepressant alone. However, Andrew Miller, a professor of psychiatry at Emory University, thought something was wrong in these small, limited studies. None of them looked at whether the participants had to have high levels of cytokines before they'd see a benefit from anti-inflammatory drugs.  "Unfortunately, much of the field has fallen into the trap of viewing inflammation as the be-all, end-all," Miller says. He and his colleagues wanted to see whether the effect of these drugs was limited to the depression patients with high cytokine levels, or if it helped all people diagnosed with depression.

Recently, my dad and I decided to take a day trip to the Florida Keys, a coral cay archipelago located off the southernmost coast of the US. I was super excited because I had not been able to go anywhere within the past nine months because of COVID-19.

With masks and hand sanitizer, we began our fun journey before sunrise. The Keys are about two hours away from where I live in Florida, so we would get there early to see the sun coming up over the ocean. On the road, we got to enjoy the Gulf of Mexico on one side and the Atlantic Ocean on the other.

When we stopped by Curry Hammock State Park, I was really amazed. The park contains 1,000 acres of land, which protects mangroves, rock land and seagrass beds that are important to the ecosyst (生态系统) in the Keys. During our time there, we were able to see some hawks flying by, and they followed the Gulf coastline of the Caribbean, migrating (迁徙) from Canada and as far south as Peru. These hawks put their wings out, "floated" up in the wide sky and then glided for long distances. After flying for thousands of miles, they still kept their fast flight patterns.

After that, we went to Key West and visited some iconic (标志性的) stops, like Duvall Street and Mile Marker 0. It was really cool because it is the very beginning of US 1, which is the longest road that runs from Key West to the Canadian border.

It was an amazing trip to the Florida Keys, and it was thrilling to have a change of scenery.
