Input: Consider Input: Article: Selfie is a photograph taken of oneself, typically with a smartphone or webcam and uploaded to a social media website. In the digital age, selfies have taken off in a way that no one could have predicted. The art of the selfie is one that lots of people have practiced and perfected in recent years. A recent study shows 91 percent of teens have posted a photo of themselves online. Some celebrities are regular selfie posters, too. It seems that selfies are more than just a trend. They are here to stay. Why are selfies so popular? The appeal of selfies comes from how easy they are to create and share. And posting selfies is popular for another reason: you can control your own image. "I like having the power to choose how I look," admits Samantha, a 19-year-old girl from Missouri, "even if I'm making a face." Actually, the most common selfie is the one where you look cute, partly because it's a quick way to get positive comments about your appearance. "If I feel pretty, I take one," says Andrew, a 23-year-old girl from Maryland, "when other people Like it, it's a mini boost of confidence." Sure, showing off a new coat or that you're at a cool event is fun, but can be a trap to fall in. There's a danger that your self-respect may start to be tied to the comments and Likes you get when you post a selfie, and they aren't based on who you are--they are based on what you look like. Seeking validation is totally normal, and it's a healthy way for teenagers to develop their identity. But with social networks, where it's easy to get quick approval almost constantly, the selfie thing can quickly go out of control. It may even start to feel like an addiction: when you get a "LIKE", you're up. But when you get nothing, your confidence can decrease quickly. Overall, opinions vary on selfie culture. It's up to you to shape the future of the habit. Ask yourself: are my selfies for fun, or do I need the comments? If you belong to the latter, it's recommended that you change your view. That could mean cutting selfies out entirely or just cutting down and making them more fun. So maybe you like to travel, or read or dance, or create crazy 3-D nail art...post them! Take it from us: it's so much more interesting.

Input: Consider Input: Article: For children with cancer ,the facts of life include the facts of death. There is always the fear that they might not live to grow up.Yet they realize that fighting cancer is the only way of beating it. So they fight.And sometimes, they win.It may take years.It certainly takes support from parents and doctors. Unfortunately, many parents can't deal with their child's illness.And doctors, no matter how caring, have other patients to care for. At times like these, the Children's Cancer Foundation can help. We are a group of Hong Kong doctors, nurses, psychologists, parents of children with cancer and concerned persons .All of us are volunteers (offer one's help without payment).We're with the children every day, listening to, and encouraging them. We also advise parents, educate the public and send doctors overseas to study new cancer treatments. Our funding (providing money) has brought better equipment to the wards (large rooms of a hospital), and paid for special flats where the children can recover. We want to do even more.But to do it, we need your help. It will be money well spent.One who looks at our past achievements should prove that. To the children, your contribution will also be a show of support.A sign that you're behind them is just the sort of news that a six-year-old chlid with cancer needs to hear.

Input: Consider Input: Article: Graham and his friends preferred to shoot up in their arms, necks and legs. A dealer once said Graham was the type who would never be able to turn back and that he expected him to die from the drug. Wendy feared the same, but didn't know how to save her son. " Once, after he'd disappeared for more than a month, I found him at a friend's house with a bunch of other users," she said, "I got down on my hands and knees, begging him to come home. He did, but the next morning he was gone. I don't know what made him do it, but I drove 20 miles to the nearest train station. Graham was headed for Seattle, his pockets full of drugs. If I hadn't gotten there in time, I would never have seen him alive again." The turning point came in 2007, after Graham was arrested yet again for possession. Wendy got a call from the Montana Drugs Project, which works with local law enforcement to keep track of youth-related crimes so it can help families in trouble. Following a counselor's advice, Wendy hired two men to come to her home in the middle of the night, tie Graham and take him to a treatment program in Thompson Falls, Montana. "I was high when they came and really angry with my mom," he said, "But if she hadn't done that, drugs would have killed me." After six months of treatment, Graham, now 19, came back to Kalispell, where he's grown close to Wendy once again. "I still have the desires every day and attend support meetings every night," he said, "But life is worth living again. My mom thinks that's a miracle. I guess she is right."
