A warm drink of milk before bed has long been the best choice for those wanting a good night's sleep. But now a study has found it really does help people nod off—if it is milked from a cow at night.

    Researchers have discovered that “night milk” contains more melatonin(褪黑激素), which has been proven to help people feel sleepy and reduce anxiety.

    The study, by researchers from Seoul, South Korea, involved mice being fed with dried milk powder made from cows milked both during the day and at night.

    Those given night milk, which contained 10 times the amount of melatonin, were less active and less anxious than those fed with the milk collected during daytime, according to the study published in The Journal of Medicinal Food.

    Night milk quickened the start of sleep and caused the mice to sleep longer.

    While the effect of cows milk harvested at different times has not been tested on humans up to now, taking melatonin drugs has been suggested to those who are struggling to fall asleep at night.

    Previous studies have also indicated that milk can be excellent for helping sleep because of the calcium content, which helps people to relax.

    Milk is also sugar-free and additive-free with nutritionists recommending skimmed milk as the best choice before bed as it is the least fattening. The more fat you take in before bedtime, the greater burden you will put on your body at night.

    Most high school students would rather spend their summer vacations far away from the classroom. But Vineet Kosaraju and Nikhil Cheerla are choosing to go back to school, and this time they are the teachers.

    "I think it's really nice that I can help the community by spending just a little bit of time every week helping just a few students here and there try and learn programming," Kosaraju said.

    Friends since they were young boys, Kosaraju and Cheerla always shared a love of computer science. They learned the skills from their parents and school, but recognized that not all children have that chance.

    "Programming isn't taught in that many schools, especially low income (收入) schools, because there isn't that much money to support it," Kosaraju said.

    So he and Cheerla developed "Math and Coding," an after-school program for kids of all ages to learn the basics of computer programming.

    Between applying for college and doing their own homework, the two boys now spend a few hours every week going to different libraries teaching classes that cover everything from building basic games to developing apps.

    The friends started the program a little over a year ago and already, it's spread to more than a dozen libraries across the Bay Area in California. They are even training volunteers to teach these very same classes in other US states and Canada.

    Maryann Mitchell brought her 8-year-old granddaughter, Gabriella, to a class on coding at the Alum Rock Library in San Jose, California.

    "It's a chance for her to learn," Mitchell said. "It's the way of the future, and it's a good way for her to get grounded and be ready for what the future holds."

    "I think the most rewarding thing is having people come up and thank you and say they really learned a lot from this class," Cheerla said. "It doesn't get any better than that."

    “Why do I live? Why do I wish for anything, or do anything? Is there anything in my life that will not be destroyed by my death?”

    These are the words of the famous Russian writer Leo Tolstoy. Like Tolstoy, many people ask these difficult questions. And they struggle to find meaning in their life. Tolstoy spent his whole life trying to answer difficult questions like these. His search for answers influenced his writing.

    On August 28th, 1828, Leo Tolstoy was born in the country of Russia.

    As a child, Tolstoy was a member of the Russian Catholic Church. But as a young man, he began to question that faith. Tolstoy wanted to make his own moral decisions; he was tired of being told what to believe. He thought people could achieve a degree of perfection if they tried hard enough. So he worked very hard at being the best in everything he did. He thought that he would find meaning and truth in success.

    In the 1850s, Leo Tolstoy wrote his first stories. He wrote about his experiences in the army He also told stories about when he was a child. These works were published and Tolstoy became a well-known writer.

    Tolstoy was finally successful. He earned the respect he always wanted. Many wealthy and intelligent men met and talked with Tolstoy. Some of the men were writers like him. They talked a lot about faith and the meaning of life. But soon Tolstoy recognized that these men were not perfect. Now he knew they could not answer his questions about faith.

    So in the 1860s, Tolstoy tried a different way to find meaning. He opened a school for the children of his serfs -the people who worked on his land. These workers were very poor. He wanted to help them because he thought they were more honest than the wealthy people he knew.

    Tolstoy learned many things from his workers. He respected how they worked hard to provide for their families. He began to believe that marriage and family would give his life meaning. So in 1862, Leo Tolstoy married a young woman named Sonya Behrs.

    The next 15 years were the best years of Tolstoy's life. It was during this time that he wrote his most famous books -War and Peace and Anna Karenina. Many literature experts say that War and Peace is one of the greatest books ever written.

    Both War and Peace and Anna Karenina communicate Tolstoy's beliefs about the Russian nation, church and people. They also communicate what he thought was the answer to all his questions. Tolstoy believed humans were supposed to live a simple lite and take care of their families. Tolstoy thought this would satisfy him and bring him happiness.

    Leo Tolstoy is still a very respected writer today. His faith and writings have influenced many people. Tolstoy's search for the meaning of life is something everyone can understand. His teachings still interest people all over the world.

    I was deeply moved by the kindness of an elderly flower seller at Sydney's Central Station one evening.

    I was feeling as cold as the winter winds quickening the steps of the people who buried chins (下巴) in scarves and hands deep into coat pockets. In many ways, 2018 had proven an arduous year. My teenage daughter had left home for university, my job of 23 years was no more, and a creative project I'd given my all to for years had also been suddenly called off. I also found out a person I considered a friend was far from it.

    A year earlier, I'd dreamt about an earthquake. In the dream, a red light flashed inside a building and then the earth began to rock. Walls fell down on me as I ran into the open, feeling sorry for the people I hadn't loved enough. Before I was buried completely by the falling world, I shouted, "Abuelo, ayudame," in my native Spanish. "Grandfather, help me!"

    Now, with the very real aftershocks of a series of unexpected endings, I walked into a little flower shop to buy a gift for a friend. The gentleman at the shop looked at me and turned away for a moment, returning with a fragrant flower. "For you. You need to smile today," he said in a rich and beautiful accent, offering me the flower with eyes full of care. It took all my strength not to cry. Then he gave me a grandfatherly hug that made me want to tell him everything.

    Instead, I thanked him and headed for the train. How did he know? I wondered. For the first time in weeks, I felt hope.

Fauja Singh, 109, who broke marathon records and was called the "Superman" before hanging up his running shoes six years ago, will be the subject of a Bollywood film, Fauja, tracing his remarkable career.

Mr. Singh, born in India in 1911, was a keen amateur runner in his youth, but gave it up. Getting over a series of personal tragedies including the deaths of his wife and two of his children, he returned to his former passion in his eighties.

He moved to the UK soon after and now lives in Ilford, east London. He arrived for his first training session in Redbridge in a three-piece suit, and his first race was the London marathon in 2000. Three years later in Toronto, he broke the world record for the 90-plus. In the early 2011, when he turned 100, Mr. Singh set eight world records in a day. He ran the 100m in 23.14, then added the 200m, 400m, 800m, 1,500m, the mile, the 3000m and 5,000m world records. Three of the events had never been attempted by anyone over the age of 100 before. Days later, he became the first centenarian (百岁老人) to complete a marathon, again in Toronto, with a time of 8:25:27.

Mr. Singh retired from competitive running in 2013 but continued jogging for pleasure. He owed his extraordinary longevity to a vegetarian diet and avoiding smoking, alcohol and fried food.

Of marathon running he has said: "The first 20 miles are not difficult. As for the last six miles, I keep talking to myself, 'Keep it up, old boy!'"
