It is said that staying up late is bad for the health. One researcher concluded that people need six hours of sleep every day. If people sleep too little, it’s bad for the health. If they sleep too much. it is also bad for the health. People who sleep less than six hours a day have a 12 percent higher risk of dying prematurely. On the other hand people who sleep more than nine hours per night regularly may live a shorter life, too. Recently, I tend to go to bed late because I study or have a chat with my friends. Sometimes I have trouble in classes because I feel very sleepy. I am a medical student, so I have to study hard, but I must also improve my lifestyle.(written by student Y, edited by Prof. Douglas Jarrell)

Nishikori Kei surprised the tennis world. He beat the number 5 seed, the number 3 seed, and then the number 1 seed Djokovic in the U.S. Open, one of the four most important tennis tournaments. He went on to the finals and played Marin Cilic from Croatia. Although Nishikori lost to Cilic, he became the first Japanese man to reach the finals in a Grand Slam tournament. People were also impressed by his racket skills. In his game against Djokovic, he bounced his racket on the court and caught it behind his back without looking at it! (by Prof. Douglas Jarrell)
