Do you want to live with a strong sense of peacefulness, happiness, goodness, and self-respect? The collection of happiness actions broadly categorized as “honor” help you create this life of good feelings.

    Here's an example to show how honorable actions create happiness.

    Say a store clerk fails to charge us for an item. If we keep silent, and profit from the clerk's mistake, we would drive home with a sense of sneaky (暗中的) excitement. Later we might tell our family or friends about our good fortune. On the other hand, if we tell the clerk about the uncharged item, the clerk would be grateful and thank us for our honesty. We would leave the store with a quiet sense of honor that we might never share with another soul.

    Then, what is it to do with our sense of happiness?

    In the first case, where we don't tell the clerk, a couple of things would happen. Deep down inside we would know ourselves as a type of thief. In the process, we would lose some peace of mind and self-respect. We would also demonstrate that we cannot be trusted, since we advertise our dishonor by telling our family and friends. We damage our own reputations by telling others. In contrast, bringing the error to the clerk's attention causes different things to happen. Immediately the clerk knows us to be honorable. Upon leaving the store, we feel honorable and our self-respect is increased. Whenever we take honorable actions we gain the deep internal rewards of goodness and a sense of nobility.

    There is a beautiful positive cycle that is created by living a life of honorable actions.

    Honorable thoughts lead to honorable actions. Honorable actions lead us to a happier existence. And it's easy to think and act honorably again when we're happy. While the positive cycle can be difficult to start, once it's started, it's easy to continue. Keeping on doing good deeds brings us peace of mind, which is important for our happiness.

    Hummingbirds(蜂鸟) are one of nature's most energetic fliers and the only birds to hover(盘旋) in the air by relying on their strength alone.

    Now scientists have found that it is the ratio(比值) of the bird's wing length to its width that makes them so efficient. The discovery is helping experts compete with 42 million years of natural selection to build helicopters that are increasingly efficient.

    David Lentink, an assistant professor at Stanford University in California, tested wings from 12 different species of hummingbirds, which he sourced from museums. He placed them on a machine used to test the aerodynamics(气力学) of the helicopter blades(桨叶). Professor Lentink's team used the same machine to test the blades from an advanced micro-helicopter used by the UK's army. They found that the micro-helicopter's blades are as efficient at hovering as the average hummingbirds.

    But while the micro-helicopter's blades kept pace with the average hummingbird wings, they could not keep up with the most efficient hummingbird's wing. The wings of Anna's hummingbird were found to be about 27 percent more efficient than the man-made micro- helicopter's blades.

    While Professor Lentink wasn't surprised at nature's superiority, he said that helicopter blades have come a long way. “The technology is at the level of an average hummingbird,” he said. “A helicopter is really the most efficient hovering device that we can build. The best hummingbirds are still better, but I think it's amazing that we're getting closer. It's not easy to match their performance, but if we build better wings with better shapes, we might match hummingbirds.”

    Professor Lentink said that we don't know how hummingbirds maintain their flight in a strong wind, how they navigate(确定方向) through branches, or how they change direction so quickly. He thinks that great steps could be made by studying wing aspect ratios-the ratio of wing length to wing width. Understanding these abilities and characteristics could be a benefit for robotics and will be the focus of future experiments.

    I now work 40 hours a week at a weather company and I love it Compared to when I became a mom, I don't feel bad about being away from my three kids. When I had my first child, I was a busy manager. My husband had a part-time job and cared for her the rest of the time. Once I became pregnant with my second kid, I quit my job to focus fully on writing.

    At first I felt like I was living the dream. I was a work-from-home mom who never had to be away from my children. But working from home can end up being more stressful than working full-time or being a stay-at-home mom.because you're frequently exhausted between work, keeping house and telling sweet faces you don't have time to play. Ever tried writing an article with a baby screaming? It was awful.

    I was so stressed that I eventually started taking my kids to 8 day care center a couple of days a week. The whole reason I worked so hard to be able to write for a living was to be at home with my kids and here I was taking them to a day care center.I thought I was a failure then.

    Over the past five years of being a freelancer(自由作家), I've realized a couple of things. As I wrote six months  ago, "I though I felt bad leaving my daughter for ten hours a day but now she is old enough to ask me to read her a story .Try telling your kid no, 20 times a day. It's cruel. You end up feeling worse for having to ignore them." I also realize not socializing with people weren't good for my mental well-being.

    Not only that, but I can now show my kids that Mom is important and has a job at a flashy office building, something they didn't realize when1 sat around in yoga pants typing on my computer all day long.

    Looking out the window of his truck, Bob Fitzgerald sees large, undesirable plants growing in the fields. Visitors to his neighborhood around the Chesapeake Bay mainly see dying forests and empty farmland. Fitzgerald says the land has been in his family since the 17th century, and it has been sinking for hundreds of years. As sea levels rise salt water is entering rivers and other waterways. As a result, the ground is becoming too salty for crops to grow.

    Around the world, scientists warn that coastal (沿海 ) farms are under threat from rising seas and salt water. A World Bank report predicts that rice production in coastal areas may fall by 15 percent by the year 2050. Another study found that hundreds of millions of people will be forced to move inland because of rising waters.

    Kate Tully, an agroecologist(农业生态学家) wants to keep coastal farmers in business as the seas rise. The United States Department of Agriculture gave Tully and other researchers $ 1.1 million to study the problem. She and her team hope to give farmers ways to stay on their land. She told media that they are testing different crops on pieces of land around the coastal areas.

    "Sorghum is my new favorite crop because it can grow without rain and it can grow with lots of rain. So this is actually a pretty good option." The grain crop may be a good choice to feed the nearly 600 million chickens raised in the area each year. As farmers know, chickens can deal with salt, dry weather conditions and heavy rains. Tally's group is also testing other kinds of grain and a few crops that they believe can grow in the salt.

    Yet just being able to grow a crop is not enough. The crop has to be profitable. So an economist on the team will be looking at the numbers. But continuing to farm the land may not be the best plan of action. Some people believe the land should he given back to nature. They say the fields should be turned into wetlands, which are popular with duck hunters. "There's money in duck hunting," fully said. Hunting organizations will pay farmers for a permit to hunt on their land. Farmers could earn a lot of money from duck hunters, she said.

    Tully and her team are just getting started. It will be a few years before they really understand how to save the farms.

Four Best Places to Travel for the Summer of 2019

    If you're still deciding where to take your summer vacation, 2019 brings major anniversaries, new flight routes, buzzy museum openings and more. In no particular order, check out our picks for where to travel this summer:

    Salar de Uyuni, Bolivia

    The Salar de Uyuni, or Uyuni Salt Flat, is a vast expanse near the Bolivian Andes that resembles ice. The surreal landscape is actually leftover salt from ancient lakes. A large lounge dome offers a public space with tables, floor cushions and hanging lanterns. Food is provided by Gustu in La Paz, considered one of Latin America's top restaurants. Beyond simply enjoying the food and scenery, guests can hike to the crater of Tunupa Volcano, mountain bike across the Salar or visit the village of Jirira. Come nightfall, on­site telescopes take full advantage of the star­flooded sky.

    Las Vegas

    There's the Park Theater, where up to 5,200 people can enjoy A­list artist residencies: Lady Gaga is currently in residence until November, with Janet Jackson and Cher starting this summer. For good measure, Bruno Mars will also be performing some dates in September. Daniel Humm and Will Guidara, perhaps best known for NYC's Eleven Madison Park restaurant, are behind the NoMad Restaurant and NoMad Bar. And foodies will no doubt want to experience Roy Choi's Best Friend, the first brick­and­mortar restaurant following his hugely successful Korean BBQ truck.

    Nova Scotia

    Nova Scotia often gets overlooked for popular provinces like British Columbia and Quebec, but its quiet charms are worth exploring. Cape Breton Island takes a bit of work to reach, but it's here that you'll find challenging hiking trails, a scenic driving route minus the traffic and real­deal Celtic culture. The Halifax Jazz Festival, held in the province's capital, is considered Nova Scotia's largest music festival, and goes down from July 9­14 on the waterfront.

    Grand Canyon

    It's the Grand Canyon's 100th anniversary as a national park, and there are multiple ways to celebrate this notable occasion. From June 22­29, stargazers can join amateur astronomers for free at the park's North and South Rims for the Star Party. Telescopes will be on hand to find planets (Jupiter and Saturn among them), star clusters and nebulae. There will also be slide show programs with a different focus each night, from protecting dark skies to learning how planets form. Constellation talks and night sky photography workshops are among the free offerings, just allow yourself enough time since you won't be the only one with this idea.
