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.

    Have you ever felt like you are not given the kind of respect you deserve? In one way or another, all of us have felt this way. We've yearned（渴望）to be looked at as an authority, someone people look up to and trust. We're not taught in school how to do this and our parents didn't tell us the secret on how to establish our authority. It's something we learn and gain by ourselves. And the answer is as simple as changing our mindset. What? No way! Oh but it is. People tend to underestimate the power of the mind. Change your game by changing your mind.

    Take time to look back and think about people in your life who are an authority or a leader at work, who has more credibility（可信度）than you or who you look up to and inspires you. They are up there not for the reasons you think. If you really think about it, they aren't the smartest of the bunch, not the most educated, and neither are they the best. And in no way do they even call themselves an expert. Instead, they are up there because they are great teachers and advocates（支持者）for the success of their customers or employees.

    Let's take Richard Simmons for example. This famous fitness personality has been a household name ever since he started gaining popularity during the first few years of his career. Stop and think, though, do you really think he is the best person to really get people into shape? Is he the Einstein of fitness and nutrition? Or does he even call himself a master of his craft? Of course not. People look up to him and give him authority because he is a great educator. Instead of sharing information that's far too complicated to understand, he figures out what your problems are and finds out a way to fix them. He even has social media that he updates on a regular basis with topics that are helpful and easy to understand for his fans and followers.

    Depending on the field you're in, you can share with people things you know and that you think they will want to know as well. If you're a nurse, for example, you can make a blog post for common health problems and quick remedies（治疗方法）people can do at home. Remember, the simpler you can make it, the better. People will trust you completely if you give them easy solutions. Like Richard, you'll soon be the expert you'll want to listen to. You can be an advocate also by showing people that you have their best interests at heart. You can also start up conferences to take up people's concerns and try to deal with them the best way that you can.

    So, how will you be viewed as an authority? Make that mind shift .Find out what concerns and troubles your target. Give solutions. Show that you care. And help them climb up that ladder of success. Ladies and gentlemen, that's how it's done.

    A Japanese company, Next Technology, has created a robot dog that can tell you how bad your feet smell, by using a powerful sensor fixed in its nose. If you feet don't have a bad smell. Hana-chan will happily wag its tail, if it's exposed to feet that are mildly smelly, it'll start to bark, and if they give off an extremely bad smell, it'll just fall over like the smell caused it to faint(昏倒).

    Foot odor (脚臭) is a big deal in Japan, where it's a custom for people to take off their shoes whenever they enter someone's home. In fact, exposing others to bodily odors can be considered annoyance in Japan. Some of the most brilliant minds in the country's tech industry have been trying to solve this problem. Last year, Thanko started selling axmpit (腋窝) fans designed to keep people's armpits nice and dry Now, we have Hana-chan.

    The robot dog has a special sensor for a nose, and can tell you if your feet smell just by sniffing them for a few seconds. According to some media reports, Hana-chan can help solve the problem of extremely smelly feet by spraying them with air freshener, but it's unclear whether this feature comes built-in, or if you'll have to pay extra for it.

    According to researchers at NextTechnology, the idea for Hana-chan was inspired by a person who desperately wanted some way to know if his feet smelled. "He told us his daughter had said his feet were smelly, " NextTechnology's Kimika Tsuji said. “But he didn't want to know how bad the odor was because he would feel hurt. That's why we developed this cute robot. "

    You may be able to make Hana-chan faint with your smelly feet, but it can have the same effect on budget-conscious people. NextTechnology plans to start selling the feet-smelling robot dog for ￥100, 000 ($9, 280) next May.

    Life can be so wonderful, full of adventure and joy. It can also be full of challenges, setbacks and heartbreaks. Whatever our circumstances, we generally still have dreams, hopes and desires —that little something more we want for ourselves and our loved ones. Yet knowing we can have more can also create a problem, because when we go to change the way we do things, up come the old patterns and pitfalls that stopped us from seeking what we wanted in the first place.

    This tension between what we feel we can have and "what were seemingly able to have is the niggling suffering, the anxiety we feel. This is where we usually think it's easier to just give up. But we're never meant to let go of the part of us that knows we can have more. The intelligence behind that knowing is us—the real us. It's the part that believes in life and its possibilities. If you drop that, you begin to feel a little "dead" inside because you're dropping "you".

    So, if we have this capability but somehow life seems to keep us stuck, how do we break these patterns?

    Decide on a new course and make one decision at a time. This is good advice for a new adventure or just getting through today's challenges.

    While, deep down, we know we can do it, our mind—or the minds of those close to us—usually says we can't.

    That isn't a reason to stop, it's just the mind, that little man or woman on your shoulder, trying to talk you out of something again. It has done it many times before. It's all about starting simple and doing it now.

    Decide and act before over-thinking. When you do this you may feel a little, or large, release from the jail of your mind and you'll be on your way.

    We don't know how different our future will be in the future. We can only try to imagine it.

    At first we think about human relationship. In the year 2050, we will use computers almost every day. We will be making new friends through the Internet—even our husbands or wives will be met in this way. It will be much faster and easier for us. On the other hand, our relationships with people won't be as important as they are today—we will feel a little lonely.

    Computers will also help us in many other activities in 2050.For example, they will be used by the children at school to make their learning easier. In addition, there will be much more other machines which will play a similar role as computers, like robots which will do the housework for us.

    Spending holidays will also be completely different. Traveling to other planets or to the moon will be available for everyone. Means of transport will, of course, change, too. We will be using solar­powered cars, which will be much more environmentally friendly.

    We could expect that the faster technological progress would lead to a more polluted environment. But it isn't true. We will pay more attention to protecting the environment. And, scientists will probably find cures for many dangerous diseases, like cancer or AIDS. Therefore, our surroundings as well as health will be in better condition.

    Although we can't predict the exact changes which will be made in the world, we often think about them. We worry about our and our children's future; we have expectations, hopes as well as fears. But I think we should be rather optimistic about our future. We should be happy and believe good things will happen.

    Western conservation groups are seeking stricter laws to deal with trade in endangered wildlife, but Dr. Paul Jepson warns that this isn't the best solution. He highlights the case of the Bali starling (八哥). Bringing in tougher laws created unexpected outcomes, which contributed to the bird's extinction in the wild in 2006.

    He said that the traditional law enforcement (执行) approach that outlawed (宣布……非法) ownership of the Bali starling in the 1980s and 1990s increased rather than reduced the demand for wild-caught Bali starlings. The bird has become a popular gift among the rich of Indonesia, who can gain more status by owning one.

    Instead, a case-by-case analysis might be needed. Last year, he said, a bird association set up a network of breeders (饲养者) among the owners of Bali starling on the island of Java. By introducing a "crowd-breeding" model, it transformed the bird into a species whose price and source of supply were publicly known. This lessened the status of keeping such birds and thereby reduced their profitability to black market suppliers.

    Another case was on Nusa Penida, an island southeast of Bali. A Balinese conservation group planned to release starlings on the island. Critics tried to block the plan, saying the island was outside the birds' native zone. Eventually, the Governor of Bali came up with a proposal. The starlings were given to a local temple as a ceremonial offering before they were released. This gave the Bali starling status as a "sacred bird", giving them protection under customary laws. Now the released starlings established a breeding population on Nusa Penida.

    Dr. Jepson commented, "I do not want to criticize the international approach seeking tighter law enforcement, but this case study shows we should not oversimplify how we respond to the problem of the wildlife trade. There is a growing body of evidence that shows more different approaches are sometimes needed to fit with the local social and political realities. We should tailor solutions on more of a case-by-case basis."
