Article: When Sara and Nathan Jones were training to become foster parents , their son, Noah, learned a tough thing or two about foster care. For instance, nearly 600 local foster kids changed families every year, and they carried their belongings from one home to the next in black garbage bags. Noah, then ten, couldn't imagine squeezing his clothes, favorite toy, and soccer ball into a trash bag and dragging it to a new house in the middle of the night. "Packing kids' belongings into garbage bags is like telling them that their stuff has no more worth than trash," says Noah. So with help from his parents and younger sisters, Macy, then nine, and Molly, then seven, Noah began to collect suitcases and duffel bags from friends and extended family; he received more than 100 bags in less than two weeks. He then sent letters to churches and put ads in local newspapers and on radio stations asking for donations. Within a few months, the family was collecting about 500 bags a week, which they stored briefly in their spare bathroom and downstairs hallway before giving them to foster care caseworkers at the Department for Community Based Services. In addition to suitcases, Noah now provides foster kids with backpacks containing shampoo, soap, a journal, and a toy--all donated. "My hope is that by giving the children things that are just theirs, they will feel a little control in the midst of the chaos," says Noah. Noah's group, A Case for Dignity, collects and distributes hundreds of bags a year. He recently convinced foster care managers from 15 Kentucky counties to pledge to use his bags instead of trash bags. "I've been so inspired by him," says his mom. "If a ten-year-old can see a problem and create a solution, how much more can we do as adults?"
Answer: To blame foster parents.

Article: After three military tours in Iraq and three in Afghanistan, Dennis Swols gets angry easily. He is unable to really talk about his time on the battlefield. But as Swols sits in a clinic at Fort Bragg, his hand drops to the furry head beside him. His mood brightens. Sitting at his feet, Lexy , a 5-year-old German shepherd, gives Swols a few moments of distraction . It's her job. And, according to Swols, she is good at it. "I have a hard time talking to people about my battlefield experiences and everything," says Swols, who took part in several wars. Now he's been suffering from post-traumatic stress disorder . "I just pet Lexy. Or I'm sitting here and we won't talk about military things. We'll just talk about the dog. My day is better every time I come in." For Doctor Christine Rumayor, Lexy is a partner and a living, breathing medical tool. The dog can calm a patient and make a therapy appointment a little more enjoyable. Animal therapy is used in only a few other army medical centers. A small number of dogs like Lexy are being used almost as co-therapists. The army is struggling to address stress disorders and mental health problems brought by more than ten years of war. One of the big difficulties is getting soldiers to seek treatment. Lexy, it turns out, is particularly good at that. Rumayor , who uses Lexy in her practice, said there was a resistance at first. "You don't expect everyone to think they can just bring their dog to work," she said. Walking around the base, she uses Lexy to attract soldiers, and then draws them into conversation. "There's nothing better than coming to an appointment where you get to have a warm furry thing that you get to pet all the time. People don't want to come in the door. When they see Lexy coming in, it makes them want to come in the door."
Answer: He is suffering from post-war stress.

Article: People who eat chocolate regularly tend to be thinner, new research suggests. The findings come from a study of nearly 1,000 US people that looked at diet, calorie intake and body mass index(BMI)----a measure of obesity. It found those who ate chocolate a few times a week were, on average, slimmer than those who ate it occasionally. Even though chocolate is loaded with calories, it contains ingredients that may favour weight loss rather than fat synthesis , scientists believe. Despite boosting calorie intake, regular chocolate consumption was related to lower BMI in the study. The link remained even when other factors, like how much exercise individuals did, were taken into account. And it appears it is how often you eat chocolate that is important, rather than how much of it you eat. The study found no link with quantity consumed. Lead author Dr. Beatrice Golomb, from the University of California at San Diego, said, "Our findings appear to add to a body of information suggesting that the composition of calories, not just the number of them, matters for determining their ultimate impact on weight." This is not the first time scientists have suggested that chocolate may be healthy for us. Other studies have claimed chocolate may be good for the heart. Consumption of certain types of chocolate has been linked to some favourable changes in blood pressure and insulin sensitivity. And chocolate does contain antioxidants which can help to absorb free radicals----unstable chemicals that can damage our cells. Mice fed for 15 days with epicatechin (present in chocolate) had improved exercise performance and observable changes to their muscle composition. They say clinical trials are now needed in humans to see if this is the case. But before you reach for a chocolate bar, there are still lots of unanswered questions. And in the absence of conclusive evidence, experts advise caution. While there's no harm in allowing yourself a treat like chocolate now and then, eating too much might be harmful because it often contains a lot of sugar and fat too.
Answer: Chocolate may help keep people slim.
