Article: I walked alongside my father, clutching his right hand.All my clothes were new: the black shoes, the green school uniform, and the red cap.They did not make me happy, however, as tins was the day I was to be thrown into school for the first time.I tried in vain lo convince him that I did nothing wrong all the way, but it didn't help. When we.arrived at the sate we could see the courtyard, vast and full of boys and girls.I hesitated and clung to his hand, but he gently pushed me from him."Be a man, "he said."today you truly begin your life.You will find me waiting for you when it's time to leave." I took a few steps.Then the faces of the boys and girls came into view.I did not know a single one of them, and none of them knew me.I felt I was a stranger who had lost his way.But then some boys began to glance at me in curiosity, and one of them came over and asked, " Who brought you? " "My father," I whispered. ''My father's dead, " he said simply. I did not know what to say.The gate was now closed.Some of the children burst into tears.The bell rang.A lady came along, followed by a group of men.The men began soiling us into ranks.We were formed into an intricate pattern in the great courtyard surrounded by high buildings. Well, it seemed that my misgivings had had no basis.From the first moments I made many friends and fell in love with many girls.I had never imagined school would have this rich variety of experiences. We played all sorts, of games.In the music room we sang our first songs.We also had our first introduction to language.We saw a globe of Earth, which revolved and showed the various continents and countries.We started lean-line numbers, and we were told the story of the Creator of the universe.We ate delicious food, took a little nap, and woke up to go on with friendship and love, playing and learning. Our path, however, was not totally sweet and unclouded.We had to be observant and patient.It was not all a matter of playing and fooling around. Rivalries could bring about pain and hatred or give rise to fighting.And while the lady would sometimes smile, she would often yell and scold.Even more frequently she would resort to physical punishment. The bell rang, announcing the passing of the day and the end of work.The children rushed toward the gate, which was opened again.I said goodbye to friends and sweethearts and passed through the gate.I looked around but found no trace of my father, who had promised to be there.I stepped aside to wait.

Article: New research at Washington University School of Medicine in St. Louis shows that people who struggle with mood problems or addiction can safely quit smoking and that kicking the habit is associated with improved mental health. Cavazos-Rehg, an assistant professor of psychiatry, found that quitting or significantly cutting back on cigarette smoking was linked to improved mental health outcomes. Quitting altogether or reducing by half the number of cigarettes smoked daily was associated with lower risk for mood disorders like depression, as well as a lower likelihood of alcohol and drug problems. "We don't know if their mental health improves first and then they are more motivated to quit smoking or if quitting smoking leads to an improvement in mental health," Cavazos-Rehg said. "But either way, our findings show a strong link between quitting and a better psychiatric outlook." In addition, she believes the serious health risks associated with smoking make it important for doctors to work with their patients to quit, regardless of other psychiatric problems. "About half of all smokers die from related to smoking, so we need to remember that as complicated as it can be to treat mental health issues, smoking cigarettes also causes very serious illnesses that can lead to death," she explained. Cavazos-Rehg and her team analyzed questionnaires gathered as part of the National Epidemiologic Study on Alcohol and Related Conditions. In the early 2000s, just under 35,000 people were surveyed. As part of the study, they answered questions about drinking, smoking and mental health in two interviews conducted three years apart. The researchers focused on data from 4,800 daily smokers. Those who had addiction or other psychiatric problems at the time of the first survey were less likely to have those same problems three years later if they had quit smoking. And those who hadn't had psychiatric problems at the initial survey were less likely to develop those problems later if they already had quit. "We really need to spread the word and encourage doctors and patients to tackle these problems," Cavazos-Rehg said. "When a patient is ready to focus on other mental health issues, it may be an ideal time to address smoking cessation, too."
