Article: Fatu Kekula is a hero. The 22-year-old Liberian nursing student, in her final year, managed to save the members of her immediate family from the Ebola virus, all without the help and convenience of a hospital. Kekula reduced the rate to 25 percent. Four of her family members were infected with the virus. Her father, Moses, her mother, Victoria, her sister, Vivian and her 14-year-old cousin, Alfred Winnie. Sadly, Kekula's cousin _ the virus. It's also impressive to note that while Kekula was treating her family members she managed to avoid Ebola entirely. On July 27, Kekula's father, Moses, went to a hospital in Kanata, after his blood pressure rose sharply. The only reason the hospital had a bed to offer him was because someone had just died. But the staff in the hospital didn't realize the patient died from an Ebola infection. Shortly, after he was admitted to the hospital, Moses developed a fever, started vomiting and was suffering from diarrhea. Once nurses started dying of Ebola, the hospital shut down and Moses had to leave. Kekula drove 90 minutes to Monrovia, the capital of Liberia, to seek treatment. Three hospitals turned them away because there is no spare bed for patients at all. Kekula made the drive back to Kanata to another hospital. They told Moses he had typhoid fever and did very little to treat him. So Kekula took him home. Once he was there, he infected three other family members. Her mother, sister and their cousin who was living with them. Kekula only lost one patient, her cousin. Her method proved so effective that international aid workers, including UNICEF, began teaching it to others in West Africa who may not be able to get to hospitals for treatment. Her father, mother and sister were already recovering when space became available at the JFK Medical Center on August 17. Alfred passed away at the hospital the next day. Kekula's father, Moses said, "I'm very, very proud. She saved my life through the almighty God."

Article: A ban on smoking in public places has come into effect on May 1,2011 in China--home to one third of the world's smokers. The ban is aimed at controlling the number of deaths from smoking-related diseases, running at a million deaths a year.That figure is predicted to double by 2020.The new smoking ban is an attempt to prevent that prediction coming true. The new rules forbid people from smoking in places like hotels, railway stations or theatres, but not including the office.Employers can warn their staff of the dangers of smoking but cannot forbid them from smoking at their desks. But the new rules have been criticized because they do not describe in detail the punishments for businesses or individuals who  _ them.Quite many smokers do not seem to take much notice of them.Often you find people smoking at next table while you are eating your meal or having a drink in a bar.In bus stops as well as in railway stations smoking can also be seen here and there.Business owners are also angry at the efforts to force them to ban smoking on their premises , because many customers refuse to go to restaurants or places of entertainment where smoking is forbidden. It appears that many Chinese people are unaware of the dangers of smoking.Research suggests that only one in four knows the harm cigarettes can cause.Officials say they have to try to persuade people not to smoke to try to reduce the numbers dying from smoking-related diseases.At the same time, however, the local governments make a lot of money from the sales of cigarettes by the state-owned firm that makes and sells tobacco products throughout the country.

Article: My father was 44 and knew he wasn't going to make it to 45. He wrote me a letter and hoped that something in it would help me for the rest of my life. Since the day I was 12 and first read his letter, some of his words have lived in my heart. One part always stands out. "Right now, you are pretending to be a timekiller . But I know that one day, you will do something great that will set you among the very best." Knowing that my dad believed in me gave me permission to believe in myself. "You will do something great." He didn't know what that would be, and neither did I, but at times in my life when I've felt proud of myself, I remember his words and wish he were here so I could ask, "Is this what you were talking about, Dad? Should I keep going?" A long way from 12 now, I realize he would have been proud when I made any progress. Lately, though, I've come to believe he'd want me to move on to what comes next: to be proud of, and believe in, somebody else. It's time to start writing my own letters to my children. Our children look to us with the same unanswered question we had. Our kids don't hold back because they're afraid to fail. They're only afraid of failing us. They don't worry about being disappointed. Their fear-as mine was until my father's letter-is of being a disappointment. Give your children permission to succeed. They're waiting for you to believe in them. I always knew my parents loved me. But trust me: That belief will be more complete, that love will be more real, and their belief in themselves will be greater if you write the words on their hearts:"Don't worry; you'll do something great." Not having that blessing from their parents may be the only thing holding them back.
