Well, parents, surprise! Lots of us are using Twitter and Facebook to thumb rides, and not just to school. It's awkward to be refused when you call a friend and ask for a ride. But with Twitter, you just look for other people heading the same way.

    It may sound risky, so many teens stay within their own social circles to find rides, and don't branch out beyond friends when asking on Twitter just like me, but to some young people, especially those taking longer trips, stranger danger is less of a concern.

    “I think the digital connection of young people is really important, because younger generations grew up sharing things on line, sharing files, photos, music, etc, so they've been very used to sharing,” said Juliet Schor, a sociology professor at Boston College.

    The sharing economy got big during the recession (经济衰退), allowing people to access more goods, services using technology and even to share costs. And that technology, for me, is what the car was for my mom, a gateway to more freedom, like what my friend Earl says, “The symbol of freedom isn't the car any more because there's technology out there connecting you to a car.”

    According to the researchers at the University of Michigan, 30 years ago, eight in ten American 18-year-olds had a driver's license compared to six in ten today. So it's not that surprising that on my 16th birthday I wasn't rushing to get a license but an iPhone.

“Driving, for young people, does mean they have to disconnect from their technology, and that's a negative. So if they could sit in the passage side and still be connected, that's going to be a plus.” Schor continued.

    To me, another plus is that ridesharing represents something, something much bigger than trying to save money. I see it as evidence that people still depend on each other. My generation shares their cars and apartments the way neighbors used to share cups of sugar. For the system to work, some of us still need our own cars. But until I get my own version of the silver Super Beetle, you can find me on Twitter.

    “My wife of 24 years, Marie Roberts, was raised in New York City, worked in the fashion industry, and never got her hands dirty,” said Keith Roberts. “Then, nine years ago, I wanted to move to Florida and reconnect to my country life, but how would I inspire（激发）the same feeling in, well, a city woman? I brought her a two-month-old potbellied pig.”

    At first sight, Marie, then 46, was smitten. So soon she took in another abandoned（遗弃）pig. And thus began Sugarloaf Mountain Farm, her animal shelter in central Florida. With the couple's two children grown up, these animals would now be Marie's babies.

    The Farm now has 300 rescues, from alpacas to donkeys, each with its own story. “A gentleman had a litter of eight pigs, and all but one died,” says Marie. “She weighed one pound and suffered great pain. For three weeks straight, I fed that baby every hour, day and night, seldom sleeping.” Till now, Marie still gets five to ten requests a day to save animals and has to turn most down. “If she can't rescue the animal, she works with that person to find a solution,” Keith says. “She's not only saving animals; above all, she's giving their owners peace of mind.”

    “A woman called from her nursing home,” Marie remembers. “Her pigs would be abandoned if she couldn't find a suitable home. 'I only have a few months, and I need to know that they'll be safe,' she said.” So Marie drove three hours and got them. Soon after, Marie received a note from the woman's daughter. “Dear Marie,” she wrote. “My mom went peacefully, as she went knowing that they are forever loved. Thank you for being Mom's angel.”

    “She is a ball of energy,” Keith adds. “A few times she's gone so far in some situations, like when she locked herself in the chicken coop（鸡舍）. I found her sitting in it with ten chicks nestled in her lap.” That is exactly what you'd expect from a true mother hen.

    "Are you going to Seattle?" an anxious-looking woman asked a female traveler at the Amtrak Airport in Sacramento. "No, I'm going to Eugene," the traveler replied. "Oh, I was hoping you could watch out for my daughter, she's never been on a plane before."

    Now, as I am quite a seasoned plane traveler, I know that seats and cars are supplied by destination（目的地）. So I came up to the woman and her frightened-looking daughter, telling them that her daughter could sit with me and that I would take care of her during the journey.

    The plane had arrived 25 minutes late, and people walked in line to get their seats. The conductor wanted to know if there were people traveling together, so I went to the front of the line with the girl and we were arranged to sit next to each other. Once on board, I showed her where to put her package, and took her to the bathroom area. Then we settled down to sleep. In the morning, I showed her the dining room and bought her a drink. She became comfortable enough to do what most 15-year-olds do: talk and text on her mobile phone.

    All through the trip, I made sure she picked up her ID, which had fallen out of her backpack, some money, which had fallen into the crack （缝隙） of the reclining seat, and continuously kept an eye on her. I hope someone takes her under their wing when she flies back to Sacramento.

    I do hope that kindness will spread around the world through these ways. We're conditioned to think that our lives go on with great moments. But great moments often catch us unaware, beautifully wrapped（包裹）in what others may consider a small one.

    Sports can help us a lot. Taking exercises can make us strong. In collective（集体的）sports like basketball, volleyball or football, we will learn the importance of cooperation(合作). And sports can also help us relax after work or study.

    However, as the saying goes, "there are two sides of everything." Sometimes we may hurt other players or ourselves if we are not careful enough when participating(参加) in sports activities. What's more, too much or hard practice can be bad for our health.

    Sports can make us healthy both physically and psychologically(心理地). It is also a good way for people to know each other and can improve friendship between people. So long as we are careful enough, sports can do us nothing but good.

    Give yourself a test. Which way is the wind blowing? How many kinds of wildflowers can be seen from your front door? If your awareness is as sharp as it could be, you'll have no trouble answering these questions.

    Most of us observed much more as children than we do as adults. A child's day is filled with fascination, newness and wonder. Curiosity gave us all a natural awareness. But distinctions that were sharp to us as children become unclear; we are numb(麻木的）to new stimulation(刺激), new ideas. Relearning the art of seeing the world around us is quite simple, although it takes practice and requires breaking some bad habits.

    The first step in awakening senses is to stop predicting what we are going to see and feel before it occurs. This blocks awareness. One chilly night when I was hiking in the Rocky Mountains with some students, I mentioned that we were going to cross a mountain stream. The students began complaining about how cold it would be. We reached the stream, and they unwillingly walked ahead. They were almost knee-deep when they realized it was a hot spring. Later they all admitted they'd felt cold water at first.

    Another block to awareness is the obsession(痴迷) many of us have with naming things. I saw bird watchers who spotted a bird, immediately looked it up in field guides, and said, a "ruby-crowned kinglet" and checked it off. They no longer paid attention to the bird and never learned what it was doing.

    The pressures of "time" and "destination" are further blocks to awareness. I encountered many hikers who were headed to a distant camp-ground with just enough time to get there before dark. It seldom occurred to them to wander a bit, to take a moment to see what's around them. I asked them what they'd seen. "Oh, a few birds," they said. They seemed bent on their destinations.

    Nature seems to unfold to people who watch and wait. Next time you take a walk, no matter where it is, take in all the sights, sounds and sensations. Wander in this frame of mind and you will open a new dimension to your life.

    Can you trust your very first childhood memories? Maybe not, a new study suggests.

    Past researches show that people's earliest memories typically form around 3 to 3. 5 years of age. But in a recent survey of more than 6,600 people, British scientists have found that 39 percent of participants claimed to have memories from age 2 or younger. These first memories are likely false, the researchers said. This was particularly the case for middle -aged and older adults.

    For the study, researchers asked participants to describe their first memory and the age at which it occurred. Participants were told they had to be sure the memory was the one that had happened. For example, it shouldn't be based on a photograph, a family story or any source other than direct experiences. Then the researchers examined the content, language and descriptive details of these earliest memories and worked out the likely reasons why people would claim to have memories from an age when memories cannot form.

    As many of these memories dated before the age of 2, this suggests they were not based on actual facts, but facts or knowledge about their babyhood or childhood from photographs or family stories. Often these false memories are fired by a part of an early experience, such as family relationships or feeling sad, the researchers explained.

    "We suggest that what a rememberer has in mind when recalling fictional early memories is …a mental representation consisting of remembered pieces of early experiences and some facts or knowledge about their own babyhood or childhood," study author Shania Kantar said in a journal news release, "Additionally, further details may be unconsciously inferred or added. Such memory-like mental representations come over time, to be collectively experienced when they come to mind, so for the individual, they quite simply are memories, which particularly point to babyhood."

    "Importantly, the person remembering them doesn't know this is fictional," study co-author Martin Conway said "In fact, when people are told that their memories are false they often don't believe it."
