Article: A new study has been carried to test the role of story telling in lowering blood pressure. Dr. Thomas Houston, a professor of the University of Massachusetts Medical School, led a group of scientists that investigated how pre-recorded videos of hypertension patients' talking about their medical histories helped another group of patients with high blood pressure to control their condition over several months. Houston was surprised by their studies that suggested that communication can be a powerful tool in medicine. They showed that those who had had similar experiences, when talking to someone with a similar background, could help change their behavior to become healthier. Hypertension is difficult to control, since it is dependent on diet, exercise and mental state. Medical treatments with drugs, and lifestyle therapies have been ly ineffective because people find it hard to follow those medical requirements. In the test, his team carefully chose their story-tellers from 230 members of a patients' community with whom they could most easily relate. Next, they divided their study population into two groups. One received three interactive DVDs containing the tellers' stories of their experiences in living with and treating their hypertension. The other were given educational discs on an unrelated health topic. The study volunteers reported that they had listened to the DVDs, and after three months, those who heard the stories of the hypertensive patients lowered their blood pressure. While the study did not _ how the story-telling influenced the patients' behavior, Houston suspects that watching patients of similar backgrounds who had a similar medical experience helped to motivate them to seek medical help to their hypertension. They found that after six months the difference in blood pressure between those who watched the story-tellers and those who observed the unrelated videos remained, suggesting that the story-telling continued to have an effect.

Article: Face book, the world's biggest social networking site, is celebrating its sixth birthday. The site's founder, Mark Zuckergerg, states that Face book will continue to work as hard as it has worked in the last six years in order to stay the web's number one communication site. The company started in a dorm room in 2004. Today it has 150 million active users, more than the 130 million of its competitor MySpace. Face book set itself apart from other social networking sites because you can communicate with people you really know and trust. Before, most people didn't want to share their real identities online. Face book has given people a safe and trusted environment for people to interact online. It has changed the way people view the world. A friend from any country is only a few clicks away. It was back in February 2004 when Zuckerberg started "the Face book" from a Harvard student's room. The aim was to help students get in touch with each other over the Internet. Within 24 hours over a thousand students had signed up and soon after that the network spread out to other universities. By 2005 a research study showed that about 85% of the students in the network had a Face book account. Another survey showed that Face book was almost as important as an iPod. At the end of 2005 Face book came to the UK. And up to today the site has been translated into 35 languages. Six years after its start, Face book has escaped the universities and colleges. More than half of its users are not at college any more and the fastest growing group are the 30 to 40-year-olds. Every day 15 million users update their profiles to tell their friends and the world what's happening to them. They also share photos, upload videos, chat, make friends, join groups and simply have fun.

Article: A traveler lost his way and got off the highway to see where he was. As he drove by, he saw rows and rows of pigpens and pigs running in fields. Suddenly, his eyes caught something really strange. It looked like a pig with a wooden leg. He drove up into the arm, where he met the farmer. " Excuse me, " the traveler said. " I was just driving by and looking at all your pigs, and I just had to stop and ask about it. Tell me, is there really a pig out there with a wooden leg?" The farmer smiled. " Oh, that would be old Caesar you saw. He's the finest pig I've ever had ---and smart! Well, let me tell you a little about that pig." " One night a couple of years ago I got to drinking and I guess I had more than I should have. I fell down and knocked over a lamp. That started a fire in the house and old Caesar smelled the smoke. He came in the back door, got the wife and kid out, roused me up and got me out. There is no question about it ---- that night old Caesar saved all our lives. You know that I'm not going to forget it too easily." " Why," the traveler said, " this is amazing! I have never heard of a pig like this before! This is fantastic!
