The U.S. Postal Service(USPS) is losing billions of dollars a year. The government company that delivers "small mail" is losing out to email and othertypes of electronic communication. First-classmail amount fell from a high point of 104 million pieces in 2000 to just 64million pieces by 2014.

    Congress permits the 600,000-empIoyee USPS to hold a monopoly (垄断) overfirst-class and standard mail. The company pays no federal, state or local taxes; pays no vehicle fees; and is free from many regulations on other businesses. Despite these advantages, the USPS has lost $52 billion since 2007, and will continue losing money without major reforms.

    The problem is that Congress is preventing the USPS from reducing costs as its sales decline, and is blocking efforts to end Saturday service and close unneeded post office locations. USPS also hasa costly union-dominated work force that slows the introduction of new ideas ormethods down. USPS workers earn significantly higher payment than comparable private-sector workers. The answer isto privatize the USPS and open postal markets to competition. With the riseof the Internet, the argument that mail is a natural monopoly that needs government protection is weaker than ever.

    Other countries facing declining letter amounts have madereforms. Germany and the Netherlands privatized their national postal companies over a decade ago, and other European countries have followed suit. Britain floated shares of the Royal Mail on its stock exchange in 2013. Some countries, such us Sweden and New Zealand, have not privatized their national postal companies, but they have opened them up to competition.

    These reforms have driven efficiency improvements in all of these countries. Additional number of workers have been reduced, productivity has risen and consumers have benefited. Also, note that cost-cutting measures—such as closing tone post offices—are good for both the economy and the environment.

    Privatization and competition also encourage new changes. When the USPS monopoly over "extremely urgent" mail was stopped in 1979, we saw an explosion in efficient overnight private delivery by firms such as FedEx.

    The government needs to wake up to changing technology, study postal reforms abroad and let businessmen reinvent our out-of-date postal system.

    Tone of voice is very important in human conversation. A person might use words that communicate one message and a tone that shows something very different. This possibility for confusion is one reason that businessmen encourage discussing things in person, rather than through email, as tone cannot be determined in the written form.

    The same rule is true with children. Children as young as a few months respond to a change in voice. It has been recorded that babies prefer to hear a story read by their own mother rather than another woman whom they do not know.

    Have you ever talked to someone who had little or no changes in their voice no matter what you were discussing? Think of the teacher or professor you had in the past that spoke in a monotone manner for the entirelecture. It is very boring and difficult to become interested in the topic.

    Parents should make an active effort to communicate with your child. If your child figures out how to open a box he or she has been struggling with and says “YES!” with pride in his or her voice, your response should be happy and excited (something encouraging, like “You did it!”). If you plainly said the same thing, you would not be matching the tone of your child.

    This applies to feelings that the child may express in everyday situations as well. If a child argues with a friend, your response should not be said in a high voice or with a smile. Seriously and sincerely you should say “You look sad” or “That must have been hard for you”.

    The tone of your voice expresses understanding, acknowledgement, connection and several other healthy things to your child. Although your words are very important, equally important is the tone with which you say those words.

    What Does the Length of Your Fingers Say About You? Are you the peace-loving type or the ambitious go-getter?

    Your finger length might be a clue. Take a look at your fingers. Would you believe me if I told you that the length of your fingers in relation to one another can predict your personality? I know that it sounds like one of those silly tests you see on Facebook, but I have to admit that it is exactly correct for me. Here's how it works.

    Look at your three middle fingers of your hand. Is your index finger longer than your ring finger? Is your ring finger longer than your index finger? Or are the two of the same length? Find the situation that best matches your hand and see if what follows is an accurate description of your personality.

Longer ring finger: The Sweet Talker

    If your ring finger is longer than your index finger, research shows that you're likely a charming type, and you can probably talk yourself out of any situation. Others often find this personality type irresistible and will go to great lengths to help you. You're more likely to take risks, and you're good at problem-solving. People in this category make great engineers, soldiers and crossword-puzzle solvers.

Longer index finger: The (Over) Confident One

    If your index finger is longer than your ring finger, chances are you are full of confidence—possibly even to the point of being over-confident and proud. You are not necessarily introverted (内向的), but you do enjoy time to yourself, especially when you're trying to complete a project. You are a dream pursuer who can make things happen, but you may be shy when it comes to taking the first step in a relationship. You are also probably happy with what you have, but you're always wishing for more.

Index and ring finger are of the same length: The Peacemaker

    If your index finger and ring finger are roughly of the same length, you are likely to avoid conflict at all costs and seek to keep the peace in your relationships. You are well-organized, faithful and sympathetic. But deep down under all of that caring and peace-loving, you also have a hot-tempered side that can appear unexpectedly when you're pushed too far. You will try your hardest to avoid a fight.

    How well do these descriptions match your personality? I was surprised at the accuracy in my case, but I'm not going to tell you which one it was!

    Why Do People Blink Their Eyes?

    People blink(眨眼) their eyes tens of thousands of times every day. Scientists have long believed blinking was an involuntary movement and served mainly to keep the eyeballs wet. But a new study suggests it has a more important purpose.

    An international team of scientists from the University of California at Berkeley studied the blinking of human eyelids. The journal Current Biology published their findings. The team said they found that blinking “repositions our eyeballs so we can stay focused” on what we are seeing. They said that when we blink our eyelids, the eyes roll back into their sockets--the bony area that surrounds and protects the eyes. However, the researchers found the eyes don't always return to the same position. They said this causes the brain to tell the eye muscles to reorganize our eyesight.

    Gerrit Maus is the lead writer of the report. He serves as an assistant professor of psychology at Nanyang Technological University in Singapore. Maus says: “Our eye muscles are quite sluggish(迟缓的) and imprecise, so the brain needs to constantly adapt its motor signals to make sure our eyes are pointing where they're supposed to. Our findings suggested that the brain measures the difference in what we see before and after a blink, and commands the eye muscles to make the needed corrections.” The researchers said that without such corrections our surroundings would appear unclear and even jumpy. They said the movement acts “like a Steadicam(摄影稳定器) of the mind.”

    The researchers said they asked volunteers to sit in a dark room while staring at a small dot on a flat surface. They used special cameras to follow the volunteer's blinks and eye movements. After each blink, the dot was moved one centimeter to the right. The volunteers did not notice this, but the brain did. It followed the movement and directed the eye muscles to refocus on the dot. After the dot was moved in this way 30 times, the volunteers' eyes changed their focus to the place where they predicted it would be.

    Professor Maus says “Even though participants did not consciously register that the dot had moved, their brains did, and adjusted with the corrective eye movement. These findings add to our understanding of how the brain constantly adapts to changes, commanding our eye muscles to correct for errors in our bodies' own hardware.”

    I think it was October, 1982. A friend had business dealings in the city of Reno, Nevada, and I was asked to accompany her on an overnight trip. While she conducted her business, I was aimlessly wandering down

    Virginia Street，heading into a most gloriously beautiful sunset. I had a strong wish to speak to someone on the street to share that beauty, but I couldn't make eye contact with anyone. Quickly I went into a department store and asked the lady behind the counter if she could come outside for just a minute. She looked at me as

though I were from some other planet and said, “Well…” Surprisingly, she followed me out.

    When she got outside I said to her, “Just look at that sunset! Nobody out here was looking at it and I just had to share it with someone.”

    For a few seconds we just looked. Then I said, “God's in his heaven and all's right with the world.”

    I thanked her for coming out to see it and sharing the beauty.

    Four years later my situation had changed a lot. I had come to the end of a twenty-year marriage. I was alone and on my own for the first time in my life. One day, while my clothes were going around, I picked up aUnity Magazine and read an article about a woman who had been in similar situation. She had come to the end of a marriage, moved to a strange community, and the only job she could find was one she disliked: cosmetic sales in a department store. We had a lot in common.

    Then something happened to her that changed everything. She said a woman came into her department store and asked her to step outside to look at a sunset. The stranger had said, “God's in his heaven and all's right with the world.”, and she had realized the truth in that sentence and that she simply had not been seeing it. From that moment on, she turned her life around.  

    ARCHAEOLOGISTS (考古学家) GUIDED BY laser images of a remote region of northern Guatemala have discovered 20-foot-high walls, watchtowers, and other evidence that ancient Maya societies had been annoyed by warfare threat over many years. The finds have upended long-established impressions of a civilization that it tamed the jungle and built thriving cities, then declined and disappeared quietly beneath the dense tropical forest.

    Among the most surprising discoveries was a large stone complex now called La Cuemavilla. Built on a steep ridge, the heavily fortified site included high walls. Moats which serves as the largest defensive system ever discovered in the region.

    This was surprising says an archaeologist, because we had a tendency to romanticize Maya warfare as something that was largely ritualized. But the fortifications were seeing suggest an elevated level of antagonism over centuries. Rulers were so deeply alarmed that they felt the need to invest in all these hilltop fortifications. There is an almost visible sense of fear in this landscape.

    All these findings owe credit to PACUNAM LIDAR Initiative, a laser survey of some 800 square miles of the Maya Biosphere Reserve in northern Guatemala. Using revolutionary Laser technology, the survey revealed the long-hidden ruins of a sprawling pre-Columbian civilization that was far more complex and interconnected than most Maya specialists had supposed.

    Guided by the new Laser treasure maps, the LIDAR team deployed through the jungle over the past year to conduct hands-on investigations of more than a dozen of the most promising sites-most of which would have been imperceptible without LIDAR.

    "You could walk over the top of a major ruin and miss it, "says an archaeologist who's part of the PACUNA project. But LIDAR picks up the patterns and makes the features pop out with surprising clarity.

    Three-dimensional maps generated by the survey yielded surprises even at Tikal, the largest and most extensively explored archaeological site in Guatemala. The ancient city was at least four times bigger than previously thought, and surrounded by a massive ditch and fortified base stretching for miles.

    Archaeologists stress that LIDAR, for all its utility, will never see below the ground or yield direct dates of occupation. "We still need to dig and hack our way through the jungle, but now we have a very accurate map to guide us."
