Article: There are many traditions around the holidays. "Holiday traditions" are things that people do every year during a holiday such as Christmas or Thanksgiving. At Christmas, for example, many people put up a Christmas tree or Christmas lights. These are Christmas traditions that have been going on for many years. But there is a "new" Christmas tradition that has become very popular: _ , a TV channel that shows nothing but a large log fire, blazing in a fireplace. People put it on their TV and it makes them feel like they are watching and listening to a crackling fire. It makes them feel calm and comfortable. The origin dates back to 1986 in Canada. At that time, not very many people knew about it or watched the channel. Today, more than three million people watch the firelog channel during the winter holiday season. That year, the firelog channel was created to give the workers in the company that is now called Shaw Cable, a break at Christmas. By running the firelog during the holidays, everyone could go home for a few days and enjoy a bit of time off. At that time, it was only broadcast to people in Edmonton but today it reaches people across Canada and beyond. This year, the Shaw firelog was updated. It is pretty high tech. Although it's still really just a fire log that has been filmed, it has its own Twitter account (@ShawFireLog), its own Facebook page and it even has a computer App so you can see the burning log on a smartphone or a tablet. The Shaw firelog will burn until Jan. 5 on Shaw Cable, channel 222.

Article: Once Dr. Mellinkoff invited me to join him at the hospital to discuss interesting cases(, ) with his students.The case at hand was a Guatemalan man, aged 34, who had a fever and many other medical problems.His condition was not improving, and there was not much hope he would live. Dr.: Mellinkoff asked to see the patient.He introduced himself in Spanish and, in a very gentle voice, asked how he felt.The patient smiled and said everything was all right.Then the doctor asked if he was able to eat.The patient said that he had no desire to eat. "Are you getting food you like?" The patient said nothing. "Do you get the kind of food you have at home?" The answer was no. The doctor put his hand on the man's shoulder and his voice was very soft. "If you had food that you liked, would you eat it?" "Yes, yes," the patient said. The change in the patient's appearance couldn't have been more obvious.Nothing was said, but it was easy to tell that a message had been sent and had also been received. Later, the doctor asked why the Guatemalan man wasn't getting food he could eat.One of the students said, "We all know how difficult it is to get the kitchen to make special meals." "Suppose," the doctor replied, "you felt a certain medicine was absolutely necessary but that our hospital didn't carry it, would you accept defeat or would you insist the hospital meet your request?" "I would probably insist," the student said. "Very well," the doctor said."You might want to try the same method in the kitchen.It won't be-easy, but I can help you.Meanwhile, let's get some food inside this man as fast as possible, and stay with it.Or he'll be killed by hunger.By the way, there must be someone among you who can speak Spanish.If we want to make real progress, we need to be able to talk with him." Three weeks later.Doctor Mellinkoff told me that the Guatemalan man had left the hospital under his own power.It takes more than medicine to help sick people; you also have to talk to them and make them comfortable.

Article: Imagine a boy from a small village in East Africa, He from a very early age has been looking after cattle. At twelve years old he knows more about cattle than most of you. However, he has never been to school. Has this boy ever had any education? Education is discovering about ourselves and about the people and things around us. All the people who care about us -- our parents, brothers, sisters, friends -- are our teachers. In fact, we learn something from everyone we meet. We start learning on the day we are born, not on the first day" we go to school. Every day we have new experiences, like finding a bird's nest, discovering a new street in our neighborhood, making friends with someone we didn't like before. New experiences are even more fun when we share them with other people. Encouragement from the people around us enables us to explore things as much as possible. As we grow up, we begin to find out what we are capable of doing. You may be good at cooking, or singing or playing football. You find this out by doing these things. Just thinking about cooking doesn't tell you if you are good at it. We learn so much just living from day to day. So why is school important? Of course you can learn some things better at home than at school, like how to do the shopping, and how to help old or disabled people who can' t do everything for themselves. At school, teachers help us to read and write. With their guidance, we begin to see things in different ways.
