　　Chocolate is good for your heart, skin and brain. Usually, people think that chocolate is bad for their health. They describe chocolate as “something to die for”or say “death by chocolate”. Now they should bite their tongues! Evidence is showing that some kinds of chocolate are actually good for you in the following ways:
　　A happier heart
　　Scientists at Harvard University recently examined 136 studies on cocoa—the main ingredient in chocolate—and found that it does seem to strengthen the heart. Studies have shown heart benefits from increased blood flow. These benefits are the result of cocoa’s chemicals, which seem to prevent both cell damage and inflammation(炎症)。
　　Better blood pressure
　　If yours is high, chocolate may help. Jeffrey Blumberg from Tufts University recently found that people with high blood pressure who ate 3.5 ounces of dark chocolate per day for two weeks saw their blood pressure drop quickly.
　　Muscle magic
　　Chocolate milk may help you recover after a hard workout(锻炼). In a small study at Indiana University, people who drank chocolate milk between workouts did better on a tiredness test than those who had some sports drinks.
　　Better for your skin
　　German researchers gave 24 women a half-cup of special cocoa every day. After three months, the women’s skin was moister and smoother. The research shows that chocolate helps protect and increase blood flow to the skin, improving its appearance.
　　Brain gains.
　　It sounds almost too good to be true, but research suggests that chocolate may improve your memory, attention span, reaction time, and problem-solving skills by increasing blood flow to the brain.

　　Short and shy, Ben Saunders was the last kid in his class picked for any sports team. "Football, tennis, Cricket—anything with a round ball, I was useless." he says now with a laugh. But back then he was the object of jokes in school gym classes in England's rural Devonshire.
　　It was a mountain bike he received for his 15th birthday that changed him. At first the teen went biking alone in a nearby forest. Then he began to cycle along with a runner friend. Gradually, Saunders set his mind on building up his body, increasing his speed, strength and endurance. At age 18, he ran his first marathon.
　　The following year, he met John Ridgway, who became famous in the 1960s for rowing an open boat across the Atlantic Ocean. Saunders was hired as an instructor at Ridgway's school of Adventure in Scotland, where he learned about the older man's cold-water exploits（成就）. Intrigued, Saunders read all he could about Arctic explorers and North Pole expeditions, then decided that this would be his future.
