A popular saying goes, “Sticks and stones may break my bones, but words will never hurt me.” However, that's not really true. Words have the power to build us up or tear us down. It doesn't matter if the words come from someone else or ourselves — the positive and negative effects are just as lasting.

    We all talk to ourselves sometimes. We're usually too embarrassed to admit it, though. In fact, we really shouldn't be because more and more experts believe talking to ourselves out loud is a healthy habit.

    This “self-talk” helps us motivate ourselves, remember things, solve problems, and calm ourselves down. Be aware, though, that as much as 77% of self-talk tends to be negative. So in order to stay positive, we should only speak words of encouragement to ourselves. We should also be quick to give ourselves a pat on the back. The next time you finish a project, do well in a test, or finally clean your room, join me in saying “Good job!”

    Often, words come out of our mouths without us thinking about the effect they will have. But we should be aware that our words cause certain responses in others. For example, when returning an item to a store, we might use warm, friendly language during the exchange. And the clerk will probably respond in a similar manner. Or harsh (刻薄的) and critical language will most likely cause the clerk to be defensive.

    Words possess power because of their lasting effects. Many of us regret something we once said. And we remember unkind words said to us! Before speaking, we should always ask ourselves: Is it true? Is it loving? Is it needed? If what we want to say doesn't pass this test, then it's better left unsaid.

    Words possess power: both positive and negative. Those around us receive encouragement when we speak positively. We can offer hope, build self-esteem (自尊) and motivate others to do their best. Negative words destroy all those things. Will we use our words to hurt or to heal? The choice is ours.

    A recent study led by researchers from the National University of Singapore (NUS) has found a clear link between the color of a taxi and its accident rate. An analysis of 36 months of detailed taxi, driver and accident data from two fleets of yellow and blue taxis in Singapore suggested that yellow taxis have fewer accidents than blue taxis. The higher visibility (能见度） of yellow makes it less difficult for drivers to avoid getting into accidents with yellow taxis, leading to a lower accident rate.

    The study was led by Prof Ho. To test whether there was a relationship between the color of a taxi and the number of accidents the taxi had, the research team analysed data collected by the largest taxi company in Singapore. The researchers found that yellow taxis have about 6. 1 fewer accidents per 1,000 taxis per month.

    They also studied the economic effect of changing the color of the entire fleet of taxis to yellow. The Singapore taxi company involved in the study owns about 16,700 taxis in a ratio (比例) of one yellow to three blue taxis. If a commercial decision is made to switch from blue to yellow taxis, 76. 6 fewer accidents will occur per month or 917 fewer accidents per year.

    Assuming an average repair cost of $1,000 per car and a downtime of six days, the color of all taxis to yellow could produce an annual saving of $2 million.

    “We are eager to continue to validate (证实) the findings of our study by looking at the use of yellow in other types of public transport, such as school buses. For example, we hope to compare the accident rates of yellow school buses against those of other colors to find out if yellow is indeed a safer color for school buses. Besides, we' re also interested to look at private-hire vehicles and do a comparison of the accident rates of vehicles that are of different colors explained Prof Ho.

    Businesses are finding more uses for Virtual Reality (VR) as the technology develops. VR is no longer only for gaming or enjoyment. An American company called Blue Goji is using VR to improve one's health by making exercise more fun.

    Blue Goji has offices in Austin, the capital of Texas. The company showed its cardiovascular (心血管的) workout machine, called the Infinity treadmill (跑步机), at the recent South by Southwest festival, an event held every year in Austin.

    A person using the treadmill wears a virtual reality headset when exercising. Before starting, the user tightens a belt to prevent falls. Then, the user plays a VR game while running on the machine. The game can transport the user into the virtual world, where he or she can be racing against virtual people.

    Recently, Leonardo Mattiazzi tested the Infinity treadmill. Mattiazzi said he had a strong feeling to actually get running and do something that pushed his limits. He said the experience was more interesting than running inside the gym without actually going anywhere.

    Constam said the active use of virtual reality helps solve a common problem while wearing a VR headset. She noted that a lot of VR experiences cause motion sickness because people are in motion during the game, but not moving in real life. But when the user is moving on the treadmill and in the game, the chances of motion sickness are reduced.

    However, users who tested the treadmill while wearing the VR headset each had a different experience. Constam said there generally is a learning curve for VR. The first time users feel lost, but "the more you do it, the more you get used to it," she said. Mark Sackler was a first time user. He said he felt a little sick at one point during the game. But he thought the experience was surprisingly realistic.

    After carefully studying the users' experiences, Blue Goji plans to make the treadmill available to the public in 2019.

The most important thing to keep in mind when deciding to serve another is that service expects no rewards. When you expect something in return, and are not serving out of the goodness of your heart, others will notice. Sure they'll thank you. {#blank#}1{#/blank#}

When you give from your heart, the real power of service comes into play. Serving is a great opportunity to strengthen your trust and respect for another, and for them to do the same to you. Not only do you feel great about helping out, but you build your relationship with them, and they will feel more willing to help you in the future. {#blank#}2{#/blank#}

However, why is service so rarely seen these days? {#blank#}3{#/blank#} Sure, living in this day and age does not leave us much time, and the last thing people want to do is more work. I'm too busy, there's too much work, or I don't have the time, " may run through your head when you hear the word service, but the truth is the benefits are worth the sacrifice. Gandhi once said that, "The best way to find yourself is to lose yourself in the service of others. " {#blank#}4{#/blank#} Some ideas of places you can serve are volunteer centers, nursing homes, boys and girls clubs, and so on. You can serve people as long as you want to.

{#blank#}5{#/blank#} Although it does take some work, the benefits are more than worth the sacrifice. Not only do you feel better about making another's day a little less stressful, but you strengthen your relationship with them and they will be more willing to help you in the future.
