Anorexia is an eating disorder where people starve themselves. Anorexia usually begins in young people around the onset of puberty. Individuals suffering from anorexia have extreme weight loss. Weight loss is usually 15% below the person's normal body weight. People suffering from anorexia are very skinny but are convinced that they are overweight. Weight loss is obtained by many ways. Some of the common techniques used are excessive exercise, intake of laxatives and not eating. Anorexics have an intense fear of becoming fat. Their dieting habits develop from this fear.

Connect to the internet in new ways

If you are baffled at the slow speeds of wifi internet when more than one device is tapped into your network you should know that radio waves are merely one part of the spectrum that can carry our data. What if we could utilize other waves to surf the internet? Harald Haas (a German physicist), has developed a solution he calls “data through illumination”—getting the fiber out of fiber optics by beaming data through an LED light bulb that alters in intensity more accelerated than the human eye can follow. Haas alleges his conception, which he calls D-Light, could develop data rates more bolted than 10 MBps, which is quicker than your common broadband connection. He foresees a time to come where information for laptops, smartphones, and pads is aired by the light in a room. And security measures would be a breeze—if you can not envision the light, you can not access the data. You are able to guess all sorts of functions for this technology, starting with public cyberspace acces...

Tomi Marjuaho assembled handsets in the last 10 years in Salo, a small town in southern Finland where Nokia, the largest mobile phone maker in the world, opened a factory in the '80s. In 2010, when Nokia started to feel the full effects of the recession, Marjuaho was fired and he has not found work ever since. "I was the only support of family and now things are getting harder," says the 39 year old man from union club, where the unemployed tend to gather in the city. "It's the same story for many friends that worked at the Nokia factory," he continued. Salo , along with many cities that have survived and developed because of Nokia investment, faces an uncertain future given that Nokia (a multinational company) moves its mobile assembly operations in Asia. Under the weight of Apple and Samsung's competition, Nokia was forced to cut production costs, which affected primarily European operations. The Finnish company has already closed...
