Article: The federal school lunch program for 30 million low-income children was created more than half a century ago to combat malnutrition . A breakfast program was added during the 1960s, and both attempted to improve the nutritional value of food served at school. More must be done to fight the childhood obesity epidemic, which has caused a frightening peak in weight-related disorders like diabetes, high-blood pressure and heart disease among young people. The place to start is schools, where junk food sold outside the federal meals program--through snack bars and vending machines--has pretty much canceled out the benefits of all those efforts. Federal rules that govern the sales of these harmful foods at school are limited and have not been updated for nearly 40 years. Until new regulations are written, children who are served healthy meals in the school cafeteria will continue to buy candy drinks and high sodium snacks elsewhere in school. Many states' school districts have taken positive steps, but others are likely to resist, especially districts that sell junk food to finance athletic program extracurricular activities, and even copier expenses. Those districts should take note of a study released in 2009 in West Virginia showing that the budgetary costs of switching from sodas to healthy drinks such as fruit juice, milk, and water were very little. Even if the switch costs money, so be it. The school should not be trading their students' health to buy office supplies. Over the last five decades, the obesity rates for adolescents have tripled. Unless there is decisive action, weight and inactivity-related disorders will bother a steady larger proportion of the work force and replace smoking as the leading cause of premature death.

What if I had the wrong music? What if I played the wrong notes? As it turned out, I was never able to answer these questions because the spotlight was waiting for me. I grasped my hands tightly together, drying off the sweat. Slowly I walked to the mud-brown piano in the centre of the room. It had 88 _ keys, which were waiting impatiently to be played. _ in my throat and sat down. Slowly, I opened the music. Next, I rested my still shaking hands on the keys. As my fingers played across the keys, I was becoming more unsure of my preparation for this moment. But the memory of my year of training came flooding back. I knew that I had practised this piece so many times that I could play it backwards if asked. Although at one point I accidently played two keys instead of the intended one, I continued to move my fingers automatically . My eyes burned holes into the page in front of me. There was no way that I was going to lose my concentration. To keep this promise to myself, I leaned forward and concentrated carefully on the music. When I came to the end of the page, a warning went off inside my head: don't make a mistake when you turn the page! Needless to say, I obeyed myself with all my heart and mind, and was proud of my "page-turning" feat . I finished the rest of the piece without making a single mistake. I had finished. I had mastered the impossible.
