Article: A programmer and an engineer are sitting next to each other on a long flight from Los Angeles to New York.The programmer leans over to the engineer and asks if he would like to play a fun game.The engineer just wants to take a nap, so he politely declines and rolls over to the window to catch a few winks. The programmer persists and explains that the game is really easy and has a lot of fun.He explains, "I ask you a question, and if you don't know the answer, you pay me $5.Then you ask me a question, and if I don't know the answer, I'll pay you $5." Again, the engineer politely refuses and tries to get to sleep. The programmer, now somewhat anxious, says, "OK, if you don't know the answer you pay me $5, and if I don't know the answer, I'll pay you $50!" This catches the engineer's attention, and he sees no end to this torment unless he plays, so he agrees to the game. The programmer asks the first question."What's the distance from the earth to the moon?'' The engineer doesn't say a word, but reaches into his wallet, pulls out a five dollar bill and hands it to the programmer.Now, it's the engineer's turn.He asks the programmer, "What goes up a hill with three legs, and comes down on four?" The programmer looks up at him with a puzzled look.He takes out his laptop computer and searches all of his references.After about an hour, he wakes the engineer and hands him $50.The engineer politely takes the $50 and turns away to try to get back to sleep.The programmer, more than a little angry, shakes the engineer and asks, "Well, so what's the answer?" Without a word, the engineer reaches into his wallet, hands the programmer $5, and turns away and goes back to sleep.

Article: Nature is full of color, from rainbows and roses to butterfly wings and peacock tails. Even the fruits and vegetables you eat have different colors: blue blueberries, red strawberries, green broccoli, and orange carrots. Plant and animals often use color to attract attention. The substances responsible for these colors belong to a class of chemical called antioxidants . Plants make antioxidant to protect themselves from the sun's ultraviolet(UV) light. Ultraviolet light causes chemicals called free radicals to form within plant cells. They can destroy parts of plant. Free radicals also have damaging effects on human beings. Some of these effects like wrinkled skin can be seen. The damage is caused by the free radicals attacking cells in our bodies. Certain cancers and heart disease are linked to free radicals. Our bodies have natural defences for fighting off free radicals. While we are young, our defences are pretty strong. However, they get weaker as we get older. The body's built-in defences can only go so far without extra help. The key to fighting free radicals with fruits and vegetables is to mix and match colors. It's like sunscreen for the inside of your body. Go for a range of very bright colors. Colorful foods contain hundreds of healthy chemicals not found anywhere else. Research into how chemicals in blueberries affect the brain's function in rats suggests that these chemicals may help our own brains work more efficiently. Don't just blame the sun. Ultraviolet light isn't the only source of free radicals. If you breathe polluted air such as smog, automobile exhaust , or wasted gas from a factory, you take in chemicals that also cause such damage. And, the body itself produces free radicals as it processes food.

Article: Have you ever wished you could solve complex math problems without thinking? What about learning to play the piano in just three days? Or mastering several foreign languages within a month? Eddie Morra, the main character in the movieLimitlesscan do all these things. But he isn't Superman or Harry Potter. Eddie has taken pills called NZT. ThrillerLimitless came out in China on October 13. In the movie, Eddie is faced with "writer's block". He hasn't written a single word of a novel, and his deadline has passed. And there's more bad news: his girlfriend breaks up with him. By chance, Eddie runs into a relative who is a drug dealer. He gives Eddie some pills called NZT that allow people to make use of 100 percent of their brains. With the magic pills, Eddie's life changes completely. He can recall everything he has ever read, seen or heard. He gains a sixth sense that allows him to predict future events. He even becomes a kungfu master by simply memorizing actions in Bruce Lee's movie. Before long he has finished his novel, won back his girlfriend and stepped into the financial world. He becomes rich incredibly quickly and is soon employed by a powerful Wall Street company. However, bad side effects are just around the corner. The effects of the pill last for only one or two days, and Eddie has to find more supplies of the pills. Meanwhile, the pills start to have other effects on him. Eddies' mind loses the ability to control the actions of his body. What does destiny hold for him? Will he be able to go back to his normal life? "Eddie's fate turns out to be a barbed joke... a sharp-eyed comic fable for an age of greed and speed." writes A. O. Scott, a movie critic with the New York Times. The drug isn't real-----yet, some researchers say such memory-enhancing drugs might not be far off. Would you take such a pill despite its side effects? Is the ability to remember everything a blessing or a curse?
