Sandra Bullock turned 51 last month. But because she looks exactly the same as she did in Miss Congeniality, a movie filmed back in the 20^th century, everyone calls her “ageless.” Bullock is just one of a number of stars in their 40s and 50s who've had birthdays recently but have not gotten older, unlike the rest of us in their age group. Take Halle Berry. One website put a photo of her 20 years ago next to one of the newly 49-year-old Berry and dared us to choose which was which. “This Is What 49 Looks Like,” it said. Seriously, if that's what 49 looks like, I must be 71.

    However, even a generation ago, famous faces evolved. Look at a picture of Grace Kelly at age 52 in the early 1980s. She looks like a beautiful middle-aged woman. Today she'd look old for her age.

    The goal now is to prevent aging while you are still young, using all the magical nonsurgical options medicine has to offer. Eventually these techniques will become less expensive, and ordinary people my daughter's age will have them. Already anti-aging is starting to be considered maintenance, like coloring your hair. My friends and I find ourselves openly debating techniques that we used to make fun of. Does fat-freezing work? How much time do you have to spend in the gym to keep the body of a 35-year-old after 50? It's all so exhausting. But members of the next generation have it tougher. They'll have to ask themselves whether they want to spend their youth trying not to get old. I've already seen “Sexy at 70” headlines. Will everyone be expected to go to their graves(坟墓) looking hot?

    I also have to wonder what else we are slowing along with age. How do you move on if you're working so hard to stay the same? And besides, if you've known the ache of watching a daughter pack up for college, you know you can't stop the clock.

    Not long ago, I tried convincing my three daughters that the world's secrets are hidden inside silence. The girls looked at me skeptically. Surely silence is nothing?

    Sitting there at the dinner table, I suddenly remembered their curiosity as children, their wondering about what might be hiding behind a door and their amazement as they stared at a light switch and asked me to “open the light”. But now they are 13, 16 and 19 and wonder less and less. If they still wonder at anything, they quickly pull out their smart phones to find the answer. None of them have any interest in discussing with me. To attract their attention, I told them about two friends of mine who had decided to climb Mount Qomolangma.

    Early one morning they left base camp to climb the south-west wall of the mountain. It was going well. Both reached the summit, but then came the storm. They soon realized they would not make it down alive. The first got hold of his pregnant wife by satellite phone. Together they decided on the name of the child that she was carrying. Then he quietly passed away just below the summit. My other friend was not able to contact anyone before he died. No one knows exactly what happened on the mountain in those hours. Thanks to the dry, cool climate 8km above sea level, they have both been freeze-dried. They lie there in silence, looking no different.

    The girls remained quiet, listening. It seemed as though they had got something.

    It is easy to assume that the essence (本质) of technology is technology itself, but that is wrong. The essence is the time we spend with our family and how much freedom we have by technology.

    Photography（摄影） is a very popular art form. Anyone with a camera – or a mobile phone – can practice it. A picture communicates in a way that words often can't. As the photographer Destin Sparks put it, “Photography is the story I fail to put into words.” And there's no better chance to practice the art of photography than during our vacation time.

    Holiday photos have been a part of the culture of travelers for a long time. For decades, vacationers have made sure they've packed a camera along with bathing suits, Hawaiian shirts and sunglasses. A camera is an important holiday item. But over the last 10 years, photography has become much more popular. It's easy to capture ( 捕捉 ) still and moving pictures of places of interest, and it's also easy to show off these pictures on social media. Armed with their smart phones, tourists, this year more than ever, are capturing the beauty of our planet.

    Of course, travel companies have caught on to this. Trekksoft has an example of photo-tourism from the United States, a land with a vast choice of beautiful locations. Antelope Slot Canyon Tours in Arizona specializes in tours of the state's famous canyons（峡谷）, which gives photographers the chance to capture them on camera.

    Most of the tourists are able to make beautiful images with just their mobile phones. Still, help is on hand from the tour guide for those who aren't great at using their cameras. These tour guides have taken a course in photography in case the skills they've learned would help their customers.

    The world's first hydrogen-powered trains have begun running in Germany. They began carrying passengers Monday in Germany's northern Lower Saxony state. The new train will run 100-kilometer trips and can travel up to 140 kilometers an hour.

    A French railroad company called Alstom built the two trains. Team in Germany and France cooperated on the project, which was supported by the German government. The new train model ,called the Coradia ilint, signals the beginning of efforts in Germany and other nations to move away from pollution-producing diesel(柴油) trains.

    The Coradia iLint is designed to run on non-electrified train lines with low levels of noise.

    It uses a process that combines hydrogen and oxygen to produce electrical power. If the system produces more energy than the train needs at that time, it can store the extra energy in batteries. The only emissions (排放物) are water and steam.

    A single tank of hydrogen can run a Coradia iLint train for about 1,000 kilometers. This is very similar to the distance a diesel-powered train can run on with a single tank.

    Hydrogen-powered trains cost more than diesel trains to build. But Alstom officials say the operating costs are much lower. The company plans to provide another 14 Coradia iLint trains to Lower Saxony by 2021.

    The head of railroad operations in the area, Carmen Schwab, praised replacing diesel trains with hydrogen. She said the move was an important first step in using clean-burning technologies to reach climate protection goals.

    Officials say the area's many wind turbines (涡轮机)will produce part of the energy to create the hydrogen to power the trains.

    Alstom says several other European countries have also expressed interest in developing hydrogen train systems. France has already said it wants its first hydrogen train to be operating by 2022.
