[Q]: Article: $? While the 2008 Olympics were the first to be broadcast entirely in HD, the 2012 Olympics are the first to broadcast in HD as well as 3D. Sean Taylor, a spokesperson for Panasonic - provider of some of the technologies - said it effectively, "Each Games, from a technology perspective, tries to have a first. London will be the first HD and 3D Games." The games were first televised in Berlin in 1936 and played on big screens about the city. Then came the first games to enter households (strictly in London that is) in 1948, followed by the first internationally televised games during the 1960 Olympics in Rome. And ever since, that feeling of physically standing in the crowd and watching these mighty contestants has only gotten clearer, more defined. Now, they more literally than ever actually compete in your living room. SS A _ is presented as the London games celebrate both the Industrial Revolution (a.k.a. the birth of pollution) and a spirit of committed environmentalism; London will be the first to actively measure its own carbon footprint during these games, designing a stadium and accommodations that cut-back on negative emissions when at all possible. They are also shooting for a world record via the "Javelin," designed specifically to keep as many exhaust pipes at bay as humanly possible.

[Q]: Article: Have you heard of the scandal that happened in one of Great Britain's biggest supermarket chains called Tesco? The British love Tesco as it sells very cheap products and it can be found on almost every corner of a British city or town. On January 15th 2013 food inspectors discovered 30 % horsemeat in a certain brand of frozen beefburgers that were mostly sold by Tesco in the UK and Ireland. In times of social media like Facebook and Twitter the news has spread fast and customers have been very concerned about what the food they buy actually contains. Tesco said it had taken away the burgers from the shop shelves immediately, and apologized to their customers. They also promised that they would find out what exactly happened and that they would work harder than ever so this would never happen again. Customers are also able to return the beefburgers and get a refund, that is, their money back. However, it will be hard for Tesco to get the people's trust back. Just imagine buying lovely beefburgers that you fry at home and suddenly you find out that you have actually eaten horsemeat! In this case not only horse lovers will be upset! By the way, why are British people so shocked about eating horsemeat? In history, horses have played great roles as working animals and as an important means of transport. When Britons of today think of horses, they think of majestic animals or cute pets rather than meat. But this is not the only reason for the protest: Customers also want to be sure that the products they buy contain what it says on the label. Hopefully, supermarkets can avoid mistakes like that in the future. Maybe there should be stricter regulations and more controls of our food? Otherwise we will soon find ourselves eating panda meat instead of pork and parrot instead of chicken. So the next time you are in a supermarket maybe check the ingredients of your food before you buy it or you could get a nasty surprise ...

[Q]: Article: I was waiting in a check-in line at Arlanda International Airport. The man ahead of me was quite a big guy. As an airport baggage handler checked through a customer at the roadside, he accidentally knocked over the man's luggage. He quickly collected the fallen bags and apologized for his mistake. However,the traveler burst into anger, shouting at the baggage handler for his carelessness. The baggage handler calmly apologized and smiled all the time. The customer continued to berate the man, even as he turned away and headed for his gate. Through it all the baggage handler smiled and remained calm. The other customers in line witnessed the incident and admired the baggage handler's professionalism and self-control. "I have never seen such restraint and humility," one of the customers sighed, "How do you keep your cool when somebody is attacking you so viciously?" "It's easy," the baggage handler answered. "He's going to London, but his bags are going to Tokyo." I won't recommend that we use revenge to relieve stress. But let me tell you about one of my friends who has found a way to go through most of his life unaffected by the _ that disturbs most people. He is one of the calmest people I've ever known and he describes how he keeps his cool no matter how turbulent a situation becomes. He says, "I look at it this way. A traffic jam has no power to make me angry. It just stops my car. And that's the way I try to look at most of what happens to me." With that philosophy, this guy goes through life with a calmness I can only envy. My friend likes to say things like, "A rude customer has no power to make me angry; he just fusses." And, "A mistake I made has no power to make me upset; it's just a chance to do better." He shows how we can truly find calmness in the midst of chaos.
