For as long as I can remember, I've always wanted a personal motto. I wanted a saying that I could really try to live my life by. I mean all the humorous book and storybook heroes always have a personal principle they follow. Good manners! Courage! Keenness! But a part of me could never get myself to create my own motto because I never knew where to start and I never thought I could give one.

    “With great power comes great responsibility.” is a quote by the great writer and philosopher, Voltaire. More familiar, it makes an appearance in the modern day movie performance of the superhero Spider-Man. This saying provides a sense of responsibility for those with actually limitless power.

    “Be good to others and others will be good to you.” is another well-known proverb that has roots in almost all of the major religions. Although it is less practiced today than it is lectured, it is a powerful and good motto to live by. Kindness, in this sense, is the final power in judging every action.

    My personal motto today has an idea – being efficient. Through my limited knowledge, I have come to find that this is simply the best way for me to give insight about who I am and what I believe in.

 Efficiency is a quality that everyone desires for, right? Who doesn't want to be able to not only work fast but to achieve great results? To some, it may appear to be a frightening journey. But to me, it means that I have a lifelong journey to improve the methods and ideas with which I come near my tasks.

    Regardless of what motto you want to live by, I believe that everyone should have one, or two or more. These are all symbols of a perfect story of us, in our own view. And it immediately provides insight to the type of person we were, we are and what we strive to be. We are never meant to be perfect, but it is important to try and live by a belief that will help us reach our potential. All you have to do is know what your excitement is and live by it.

    Mr. Jackson was tired of living in his old house in the countryside and wanted to sell it and buy a better one. He tried to sell it for a long time, but was not successful, so at last he decided to go to an estate agent（房产经纪人）.

    The agent advertised the house straight away, and a few days later, the owner saw a very beautiful photograph of his house, with a wonderful description of his garden in an expensive magazine.

    Having read the advertisement through, the house owner hurried to phone the estate agent, saying, “I'm sorry, Mr. Jones, but I've decided not to sell my house after all.” “Why?” the agent asked in a surprised voice. “Because from the advertisement in that magazine I can see it's just the kind of house I've wanted to live in all my life.”

    Crossing your legs is an extremely common habit; most people don't even notice that they're doing it when they sit down. While you may find it comfortable to sit with one knee crossed over the other, it might be causing health problems that you are not aware of.

    A study published in Blood Pressure Monitoring stated that sitting with your legs crossed can increase your blood pressure. The reason for this is that the blood in your legs has to work against gravity to be pumped back to your heart and that crossing one leg over the other increases resistance(阻力), making it even harder for the blood to circulate. This causes your body to increase your blood pressure to push the blood back to the heart. You won't feel any immediate effects, but repeated, drawn-out increases in blood pressure can cause long-term health problems. So, planning to sit for a long period of time? Don't keep your legs crossed.

    Crossing your legs at the knee can also cause pressure on the major nerve in your leg that passes just below your knee and along the outside of your leg, explains Richard Graves, a medical expert. This pressure can cause numbness and temporary paralysis (麻痹) of some of the muscles in your foot and leg, preventing you from being able to raise your ankle—what we know as that “pins and needles” sensation. While the feeling of discomfort may only last a minute or two, repeatedly crossing your legs until they feel numb can cause permanent nerve damage.

    So next time you sit down, try to get yourself in the habit of sitting with both of your feet on the floor. Not only will it help your posture and stability, but it will also save your health in the long run.

    Here are some of the strangest aviation(航空)ideas in recent history.

    Double-Decker Seating

    In 2015, Airbus filed a patent for a design for a double-decker cabin seating arrangement. Passengers would sit on top of the other, with upper-tier passengers climbing steps or a small ladder to reach their seats. While the design does have some advantages, the idea of climbing a ladder during flight seems unreliable.

    Separated Cabins

    This patent was awarded to Airbus. Rather than waiting for a flight to arrive and be cleaned,passengers could simply board a ready cabin, which would be moved into the plane's body as soon as it was ready. When the plane reached its destination, the cabin would be separated again. Different cabins with different kinds of seating or levels of comfort could be used for flights of different lengths or destinations.

    Windowless Cockpits(驾驶舱)

    For ideal design, airplane noses should be long and pointy. But there's the whole "pilots have to fit in the cockpit" problem. Well, what if the cockpit didn't have to go in the nose of the plane? That's part of the thinking behind this Airbus patent application* which suggests replacing the plane's window with a digital viewing surface. Without a window, there's no reason the cockpit needs to go in the front of the plane —it could go in the middle of the plane, or even in the tail.

    Nap Straps (睡眠吊带)

    Airbus is not the only company in the strange patent contest. Boeing's got its own patent, Nap Straps. With this invention, passengers looking for a nap can find an "upright sleep system^" beneath their seat. In action, the whole thing is somewhat like a traction device for someone who's been in a terrible accident.

    Madame Marie Curie famously won two Nobel Prizes, but many other women have also been awarded the prize, too. Here are their stories.

    Selma Lagerlof

    Selma Lagerlof was a Swedish author and teacher. She published her first novel, Gosta Berling's Saga, at the age of 33. She was the first female writer to win the Nobel Prize in Literature which she was awarded in 1909. Additionally, she was the first female to be granted membership in the Swedish Academy.

    Gerty Theresa Cori

    Gerty and her husband, Carl Cori, met in Prague and lived in Austria before immigrating to the United States in 1922, where the two medical doctors worked together at Roswell Park Comprehensive Cancer Center in New York. In 1947, Gerty and Carl were awarded the Nobel Prize in Physiology or Medicine, making Gerty Cori the first woman to hold the honor.

    Maria Goeppert-Mayer

    In 1942, Maria Goeppert-Mayer joined the Manhattan Project. From there, she moved on to Los Alamos National Laboratory, then to Argonne National Laboratory, where Goeppert-Mayer developed the nuclear shell model. For this, she shared the 1963 Nobel Prize in Physics with J. Hans D. Jensen and Eugene Paul Wigner.

    Dorothy Crowfoot Hodgkin

    Dorothy Hodgkin's mother encouraged her love of science as a child, and at age 18, she began studying chemistry at a women-only Oxford college. Her work on mapping vitamin B12 earned her the Nobel Prize in Chemistry in 1964.

The Kendama World Cup

Old-fashioned fun is making a comeback!

Many kids are putting down their electronic devices and picking up an ancient toy. It is called a kendama, and it possibly dates back to the 16th century.

The kendama is a small wooden hammer with three cup-shaped ends and a spike on top. A wooden ball with a center hole is attached by string to the hammer. The goal is to make the ball land in a cup or on the spike. It sounds simple, but there are over 1,000 kendama techniques and tricks to master.

The game's popularity began to grow after the Japan Kendama Association was started in 1975. Today all ages participate in various competitions, including the Kendama World Cup(KWC).

The two-year-old event, which opens in Hatsukaichi, attracts people from all over the world. Players choose 10 different tricks from an approved list. They are then awarded points corresponding to the level of each trick.

A new Kendama World Cup winner will be named tomorrow in this popular sporting event.
