On the eve of our daughters' weddings, I gave both of them what Iconsidered to be excellent marital advice: never leave your husband unsupervised(无人监督的) with pruning shears (修枝剪).

If only I had taken my own advice. I recently let my guard down. Thirty-some years of marriage can do that toa woman. Give a man pruning shears and electric trimmers (电动修剪器) and he will givenew meaning to “armed and dangerous.”

One day earlier this year, my husband saidthat the crab apple tree was dead.

“Why do you think it is dead?” I asked.

“Look at it. There's not a leaf on it.”

“There's not a leaf on anything. It'sMarch,” I said.

“It looked sick last fall and with thisbitter winter we had, I'm convinced it's dead.”

The truth is he's never liked thecrabapple. Sure, it has beautiful blooms in the spring, but then it gets adisease, the leaves curl, and it drops those little apples that sit on thedriveway.

Each passing week he pronounced the treedead. Eventually I began to believe him. Though he agreed it would be aregrettable loss, there was a twinkle in his eye. He armed himself a couple ofweeks ago and began trimming. A branch here, a branch there, a small limb, thena large limb. I watched and then decided to check the wood on some of thebranches closer to the trunk. I broke one off and saw green.

The crabapple was not dead. It just hadn'thad time to leaf out. The tree was now falling to one side, but it was notdead. I would have told him so, but he had moved on to a maple. Once the manstarts, he can't stop. One trim leads to another.

“Please, stop!” I called.

He smiled and nodded, but he couldn't hearbecause he had started the hedge (树篱) trimmers and was getting ready to fix a line of hedges.

Zip (飕飕声), zip, zip.

“What do you think?” he shouted.

“It's supposed to be a privacy hedge; nowall that will be private are our ankles.”

He started the trimmers again.

“Stop!” I called, “Come back!”

“Why?” he shouted.

“You're in the neighbor's yard.”

    Airbags, now found in almost every vehicle, have saved countless lives and largely reduced the severity of injuries in crashes. Similar technology could greatly reduce broken hips (髋部) resulting from a fall, something most seniors fear.

    Dr. Robert Buckman and his start-up company, Active Protective in Allentown, Pennsylvania, has developed a promising solution, a wearable airbag that can protect hip bones in the event of a fall. The idea was the result of Dr. Buckman's years as a doctor at Temple University. He noticed how many elderly people were being brought into hospitals with broken hip due to falls, and how they often never completely recovered from the injuries. He started to ask what he could do for these people, and that was when he started trying to figure out whether there was a way of helping people who were at the highest risk of falling and suffering these kinds of injuries.

    The device is worn much like a regular belt, but on the outside of the clothing, and it includes sensors that monitor the movement of hips. If the device detects that the person, is falling, an airbag opens before the person hits the ground, cushioning the fall. When the wearer hits the ground, the bag reduces the force to the hip bones by 90 percent, enough to avoid the majority of hip injuries.

    With one out of every three people aged 65 and older suffering serious falls each year, Active Protective has a big market for its wearable device. It also has the potential to sizably reduce hip - related health care expenses: Hip injuries among the elderly cost the US health care system in 2012 $30 billion, which doesn't include the long-term care expenses associated with the high percentage of patients that can no longer live independently.

    It was May 23, 2016. Arnot, the 32-year-old mountain guide, reached the top of Everest without the use of oxygen (O₂) equipment. It was achieved after seven years, three previous attempts, and fourteen straight hours of climbing.

    After 15 minutes at the top, Arnot began her descent (下坡). Eight hours later, she reached the camp at 7, 600 meters and became the first American woman-and only the seventh woman ever—to successfully reach Mount Everest without oxygen equipment.

    "There are so many reasons for her impressive achievement, especially the physical and emotional efforts that she's put forth over the years to make this happen," says the professional climber and photographer Richards, "The mental courage that it requires is something very few people have."

    Arnot didn't start climbing until she was 19 years old. Money was tight in her family, and climbing mountains never occurred in her mind. After graduating from college, Arnot was invited by her friend to climb a mountain. "It totally changed my life, says Arnot. I always know that if you want something, you can achieve it, but knowing what you want is a whole different thing," she says. "I am athletic but not competitive. After my first climbing, I knew immediately that mountains are what I want—as that is where I felt home for the first time in my life."

    After that first climb, she devoted herself to learning how to climb and move through mountain. It was during her second trip to Everest in 2009 that she first set her sights on a no-oxygen attempt. However, while hiking into Everest Base Camp that year, she hurt her leg and wasn't able to climb without oxygen. In 2013 she nearly made it to the top, but was forced to take oxygen at 8,504 meters while helping another climber.

    When Arnot finally stood atop Everest, she called her best friend, "I reached the top and I'm not using any oxygen." Then, tears began to stream down from her eyes. So much of Arnot's life has been about pushing the limits of her abilities, and in this case, she's also pushed up against the outer limits of the human spirit.

    Consumer electronics once again topped the list of the most wanted gifts this holiday season.

    "Seventy-six percent of consumers who plan to buy holiday gifts say that they will spend money or buy at least one technology product; definitely a solid vote of confidence for technology."

    Steve Koenig is with the Consumer Electronics Association. He says the group's latest research also shows that Americans this year are spending more on technology products. "Here in 2012, $252 on average the technology spend for consumers this year."

    From tablet computers to smart phones, American shoppers have been lining up to get the newest and coolest electronic devices on the market. There are more choices today than ever before. "It's kind of hard to make a decision."

    Tablet computers are one of the best-selling products this year. Brian Tong is Senior Editor of CNET.com. The website reports on tech news and examines the latest electronic products. He says the Apple iPad Mini is one of the most popular tablets. Its starting price is $329. One of Apple's biggest competitors is the Google Nexus 7. It starts at $199.

    "Its hardware is more powerful than what's in the iPad Mini, but also it offers you a lot of things like maps that work better than Apple's maps.

    But Brian Tong says there is one reason why people may like the iPad Mini more than the Nexus 7. "If you just want to read books and surf the Internet, you don't really need to get an iPad Mini, but if you want the largest robust group of apps (应用软件) that's where the iPad and Apple's ecosystem shines the most."

    Elman Chacon is with the electronics store Best Buy. He says another hot product this season is smart cameras. They connect to the Internet through Wi-Fi. This makes it easy for users to email or upload photographs directly from the camera." You can literally take a picture and upload it into your Facebook in a matter of seconds. These things are pretty cool because they do a lot of things."

    Streaming media boxes also connect to the Internet. People are able to watch web content such as movies and YouTube videos on their televisions. Another popular item is wireless speaker systems. The newest ones work with any device that has Bluetooth technology, including smart phones, laptops and tablets.

    Nhon Ly, a 55-year-old Vietnamese-born professional bodybuilder from California has been awarded the "real-life Master Roshi" for his unbelievable similarity to the popular Dragon Ball Z anime(日本动漫) character.

    Ly certainly doesn't look like any other typical 55-year-old man. In fact, he looks a lot better than most guys in their 20s, with his lean(瘦且健康的), strong muscles and youthful attitude. But he's absolutely not the only 50-something man who has the strong muscle in the world.  What really sets Nhon Ly apart from all the rest is his unbelievable similarity to Dragon Ball Z character Master Roshi, also known as the Turtle Hermit, in his "final form". And he apparently liked the comparison so much that he even set his Instagram handle as @master_ roshi_ real_ life.

    According to Madness Media, Ly immigrated to the United States in 1980, at the age of 16. He got a job as a pedicurist(修脚师) at a nail salon, and worked his way up to salon owner. Although he has achieved so much, bodybuilding has always been his biggest love. He has competed in several professional bodybuilding events, with his most notable results being the 4th place at the 2011 US Championship, the 7th place at the 2012 edition, and the 5th place at the 2015 Nationals.

    Even at 55, Nhon Ly continues to train hard in the gym in order to keep his Master Roshi look. He also likes to share photos and videos with his 40,000 fans, many of whom are Dragon Ball Z fans. They routinely post a large quantity of comments, thanking him for training Goku, who is the main character in Dragon Ball media, and asking him to train them in the art of bodybuilding.
