On October 31st, 2009, Chinese famous scientist Qian Xuesen, died in Beijing when he was 98 years old. He is famous as “the country's father of space technology and king of rocketry”.

    Qian was born in 1911 in Hangzhou. He left for the United States after winning a scholarship to graduate school in 1936. He studied at the Massachusetts Institute of Technology and later at the California Institute of Technology.

    Qian began his career in the US and was regarded as one of the brightest minds in the new field of aeronautics（航空学) before returning to China in 1955.

    After he returned, Qian set up the first missile（导弹）and rocket research institute（学院) of China. The institute later helped start Chinese space program. He led the development of China's first nuclear-armed ballistic missile (弹道导弹) and worked on its first satellite.

    He retired in the year before Chinese manned space program was launched in 1992. But his research formed the basis（形成基础）for the Long March CZ -2F rocket that carried astronaut Yang Liwei into orbit in 2003.

    In August, 2009, Chinese Premier Wen Jiabao visited Qian and praised him for devoting his life to Chinese defense technologies. Qian told him, “I'm trying to live to be 100 years old”.

    I wasn't surprised when I read that actress Helen Hunt recently stated that she would never allow her young daughter to become a child star. Ms. Hunt is the daughter of a Hollywood technical director, and grew up in Hollywood. Now in her late 40s, she started acting and modeling when she was eight and has probably seen a lot over those years in show business.

    She has had a successful career. She earned four Golden Globes and four Emmys. She also attained the top honor of her profession when she won the Best Actress Academy Award for her role in the 1992 movie, As Good As It Gets. Given those accolades, Ms. Hunt is successful. There is no doubt that her early experiences as a child star prepared her for what has been an outstanding adult career. Given those achievements, why would this star declare she'll never allow her daughter, now at the age of six, to follow in her footsteps?

    Everyone familiar with the entertainment scene is aware of the reasons for her attitude. Recent tabloid (小报) news headlines featuring the troubles of former child stars, among them Lindsay Lohan, Britney Spears and the late Gary Coleman, may answer the question. Although Ms. Hunt managed to become a successful grown-up star, she apparently believes she's an exception.

    What Ms. Hunt may be suggesting is that many very young stars go through unnatural childhoods on movie and TV sets. While they're earning big incomes, they're so pampered (纵容) by directors and praised by fans; they may get false impressions that their lives will always be that way. Then, within a few years, when faced with reality, they're hurt and confused. After all the overwhelming affection, they find they can't deal with the problems. That's often when drugs and alcohol take over their lives.

    Helen Hunt has some other reasons why she doesn't want her daughter to be in the entertainment business. Many child stars can never make a successful transition to meaningful adulthood. However, as with many Hollywood movies, I believe there are both good and bad scenes about how it can be played out in real life.

    Being sociable looks like a good way to add years to your life. Relationships with family, friends, neighbors, even pets, will all help, but the biggest longevity (长寿) seems to come from marriage. The effect was first noticed in 1858 by William Farr, who wrote that widows and widowers (鳏夫) were at a much higher risk of dying than the married people. Studies since then suggest that marriage could add as much as seven years to a man's life and two to a woman's. The effect can be seen in all causes of death, whether illness, accident or self-harm.

    Even if the chances are all against you, marriage can more than compensate you. Linda Waite of the University of Chicago has found that a married older man with heart disease can expect to live nearly four years longer than an unmarried man with a healthy heart. Similarly, a married man who smokes more than a pack a day is likely to live as long as a divorced man who doesn't smoke. There's a flip side, however, as partners are more likely to become ill or die in the couple of years following their husband or wife's death, and caring for your husband or wife with mental disorder can leave you with some of the same severe problems. Even so, the chances favor marriage. In a 30-year study of more than 10,000 people, Nicholas Christakis of Harvard Medical School describes how all kinds of social networks have similar effects.

    So how does it work? The effects are complicated, affected by socio-economic factors, health-service provision, emotional support and other more physiological mechanisms(生理机制). For example, social contact can promote development of the brain and immune system, leading to better health and less chance of depression later in life. People in supportive relationships may handle stress better. Then there are the psychological benefits of a supportive partner.

    A life partner, children and good friends are all recommended if you aim to live to 100. The overall social network is still being mapped out, but Christakis says: "People are inter-connected, so their health is inter-connected."

    Professional athletes pay a high price for their pursuit of excellence and glory. Training to the limit tears muscles and wears out joints. Gymnasts often need hip replacements when barely into middle age. Few footballers make it to the end of their careers with their knees intact.

    But many also run a darker risk: doping—the use of banned athletic performance-enhancing drugs by athletic competitors. The Winter Olympics in Pyeongchang, in South Korea, starts this week in its shadow. Years after whistle-blowers first revealed wholesale (大规模的) doping in Russia, the International Olympic Committee (IOC) at last decided to bar it from taking part. But it has allowed many Russians to compete as individuals. And on the eve of the competition the Court of Arbitration for Sport (CAS) said that 28 others should receive a more tolerant penalty from the IOC, further muffling the anti-doping message.

    Russia's doping is unusual only in its scale and institutional nature. No country or sport is immune. Studies, and an anonymous survey at the World Athletics Championships in 2011, suggest that a third of athletes preparing for big international competitions take banned substances. Yet just 1-2% fail a test each year. Lance Armstrong, a cyclist who won the Tour de France seven times and later admitted to doping all the while, was tested on 250 occasions. The few times he failed, he avoided punishments by claiming he had taken anti-inflammatories (消炎药) for saddle-sores (骑行引起的肌肉酸痛).

    Doping is more sophisticated than when some states used steroids (类固醇) to bulk up athletes. New drugs are designed to be undetectable in a blood or urine sample. Many athletes "blood dope," receiving transfusions or taking a drug that stimulates the production of red blood cells to improve their physical strength. Soviet athletes who were fed steroids suffered a host of serious problems in later life. They were more likely to commit suicide, or to miscarry (流产) or have a disabled child. No one knows what risks those taking new "designer" versions are running. Blood-doping can cause heart attacks; more than a dozen cyclists' deaths have already been linked to it.

    The agencies that set out to stop doping are hugely outclassed. As the argument over punishments on Russia illustrate, they are divided and weak. Most testing is done by national bodies, which may not try very hard to find evidence that would get their own stars banned. The World Anti-Doping Agency (WADA), which oversees them, is packed with officials from national sports federations and the IOC. Their interests are likewise conflicted. Its budget is tiny. The system seems to be designed to look tough but punish only the occasional scapegoat (替罪羊). Honest athletes deserve better.

    Paddle through Big Rideau Lake (part of the historic Rideau waterway) to access 14 backcountry campsites. Most are located 5-45 minutes away from the boat launch. You'll find a picnic table, tent space, and a pit toilet nearby each site. Paddle back to visit Murphys' piece of living history: the Mica Mine!

    Remember: backcountry travel requires careful consideration of packing, route planning, meal planning, safety, and your skill level.

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.
