Article: Nowadays with the development of agriculture, farmers use more technology. However, they are being told more needs to be done to stop them injuring at work. One in five British workplace deaths happens in agriculture even though farmers are only a small part of the working population. During the year 2012/13 there were 1,061 injuries in total and it is thought many more go unreported. Jim Chapman from Warwickshire had his arm torn off by farm machinery seven years ago when he was 23. "You don't realize how much you rely on your second arm until it's gone," he said. He fell against a PTO shaft , a spinning metal bar at the back of a tractor. "It catapulted me from one side of the machine to the other," he said. "I landed on the floor, minus all my clothing. My left arm had been torn off." He admits that the machinery was missing part of its proper safety guard. "But again," he added, "it was a rushed day. There were a few machines that didn't work. Also, I was getting behind with the jobs." Over the last 10 years, other industries that you'd think of as dangerous, like building or quarrying , have lowered the number of workplace deaths and injures. In the farming industry though, deaths remain high with 34 deaths in 2012/13. Judith Hackett, the chair of the Health and Safety Executive (HSE) says it is "not acceptable" that the accident statistics for farming are still high. "People in farming don't have minor injuries. When they get injured, it's bad." She said. "When I said to the National Farmers' Union (NFU) that if I had sons I would not want them to work in agriculture, it really made them sit up and take notice." There's a whole host of reasons why farming is as dangerous as it is. It is a very rough industry. Also, it's often because people are left alone. They could be young and inexperienced, or older people, who would have retired maybe 5 or 10 years ago in other industries. Jim wants others to learn from his experience. "Look at what you're doing before you go running in," he said. "You could make a mistake that you'll live with for the rest of your life."

Article: DALLAS - A suburban Dallas woman accused of killing her two young children told a 911 operator that she first tried to poison them because they were autistic and she wanted "normal kids," then choked them with a wire until they stopped moving, according to the recorded call. Irving police on Wednesday released recordings of the 911 call after Saiqa Akhter was charged with capital murder in the death of her 5-year-old son, Zain Akhter and her 2-year-old daughter, Faryaal Akhter. Police said the children were attacked at the family's apartment Monday night. In the recording released Wednesday, the woman identified herself as Saiqa Akhter and repeatedly told the operator she killed her two children. At one point, the woman hung up and the dispatcher called her back. "I killed both of them. I told you," she told the operator. Later, she explained that both children were lying motionless on the bed in the master bedroom. "They are not doing anything. They are just blue and they are not taking any breaths and ... their heart is not beating," she said. She told the operator she initially tried to poison the children with bathroom cleaner but they refused to drink it. When that didn't work, "I used a wire on their necks," she said. When the operator asked the woman why she attacked her children, she said, "They're both not normal, not normal. They're autistic. Both are autistic." Pressed further, she said, "I don't want my children to be like that. ... I want normal kids." Later, the dispatcher asked the woman what she was feeling. "Nothing," she responded.

At the end of the recording, police can be heard arriving at the home.

Every day on my way to work I would buy a newspaper from an elderly gentleman on the corner of the street.He would always smile and say,"Good morning."His smile always made my day. Most of the people who sell these papers are homeless or poor and they do it to make a few bucks. One day Charlie wasn't there!Someone else was in his place! This other guy told me Charlie was in the veterans' hospital. It troubled me all day long.All I could think about was Charlie being alone in the hospital.I never knew he was a veteran who had served our country.I just knew his smile always made my day. I asked my girlfriend if she would go with me to visit him and she agreed.When I showed up in Charlie's room he began to cry.He told us he had been feeling very lonely and was convinced no one would ever visit him.He said that we were his only visitors. We told him we were glad to do it and thanked him for all that he had done for others. I never saw Charlie after that,although I heard he moved to California.That was thirty years ago but I haven't forgotten my smiling friend.A big thankyou to those who serve our country and protect us and thank you Charlie,wherever you are!
