    Throw out the bottles and boxes of drugs in your house. A new theory suggests that medicine could be bad for your health. This new theory argues that healing (the process of becoming healthy and strong again) is at our fingertips: we can be healthy by doing Reiki on a regular basis.

    Supporters of medical treatment argue that medicine should be trusted since it is effective and scientifically proven. They say that there is no need for spiritual methods such as Reiki, Yoga, Tai Chi. These waste our time, something that is quite precious in our material world. There is medicine that can kill our pain and x-rays that show us our broken bones. We must admit that these methods are very effective in the examples that they provide. However, there are some "everyday complaints" such as back pains, headaches, which are treated currently with medicine. When you have a headache, you take an Aspirin; when you cannot sleep, you take Xanax without thinking of the side effects of these. When you use these pills for a long period, you become dependent on them; you cannot sleep without them. We pay huge amounts of money but never get better. How about a safer and more economical way of healing? When doing Reiki to yourself, you do not need anything except your energy so it is very economical. Also, there are no side effects and it is scientifically explained.

    They also claim that serious illnesses such as HIV/AIDS and cancer cannot be treated without drugs. They think so because these patients spend the rest of their lives in the hospital taking medicine. How can Reiki make these people healthy again? It is very unfortunate that these patients have to live in the hospital losing their hair and weight because of the side effects of the medicine they take. Actually, instead of drugs which are expensive and have many side effects, you can use your energy to overcome the hardships of life, find an emotional balance, leave the stress of everyday life and let go of the everyday worries.

    Some people may still hold that in our material world, everything depends on time. How would it be possible to find time to do Reiki? In fact, Reiki does not require more than 15 minutes of our time. It is less time consuming than medicine if we think of all the time we spend taking medicine for some complaints and taking some more for the side effects as well.

    How Fit Are Young Teens?

    How often do you exercise? A new study finds that most kids ages 12 to 15 aren't getting enough physical activity.{#blank#}1{#/blank#}

    U.S. fitness guidelines recommend (推荐) an hour or more of physical activity every day. According to the study, only 1 in 4 U.S. kids meet the recommendation. Few kids in the survey met the guidelines for physical activity that raises the heart rate and makes you breathe harder. However, most of those kids said they did at least an hour of exercise at that level during the previous week.{#blank#}2{#/blank#}

    The study found fat teens were less active than normal-weight girls and boys. Overweight girls were slightly less active than normal-weight girls.{#blank#}3{#/blank#}

     “There's always room for improvement,” said health expert Tala.{#blank#}4{#/blank#}She also said the results provide useful information to help with fitness campaigns such as Let's Move, which was launched by First Lady Michelle Obama. To inspire kids to eat right and get in shape, the First Lady visits schools and holds exercise events. She also calls on schools to offer regular gym classes.

    The research suggests kids who get physical education may get better grades.{#blank#}5{#/blank#}

A. It's concerning.

B. She is an expert on children's health.

C. She was the lead author of the study.

D. The results are based on about 800 kids.

E. Schools should give kids more time for physical activity.

F. But levels were similar among overweight and normal-weight boys.

G. Overall, about 25% said they got an hour of that kind of difficult exercise every day.

This year's flu season is pretty scary. To try to minimize the effects, public officials are still urging anyone who hasn't yet gotten their flu shot to get one as soon as possible. However, even if every single person got a shot in the arm, the vaccine(疫苗)— with its excellent 36 percent effectiveness—would not prevent everyone from getting infected with the annoying virus. Knowledge is power, so here's what goes on in your body when you come down with the flu.

    The influenza virus primarily attacks your nose, throat, and the tubes that lead to your lungs. But the flu is so much more than that. Your muscles ache, your head hurts, and your appetite goes down, among other things. To our surprise, almost all of these symptoms have less to do with the virus itself than with your immune(免疫的)response to them. Unfortunately, the very defense you have in place to ge rid of the flu is the reason you feel so painful when you recover.

    The virus usually enters through your mouth, typically by way of your hands. But it takes a few days for symptoms to set in. While this process might cause some harm to your nose and throat, it's nothing major, and nothing like the symptoms that typically accompany a bad or even mild case of the flu.

    The real fun starts when your immune system begins to fight. Your immune system comes in two parts: the innate system and the adaptive. The innate immune system is essentially an all-purpose tool. As soon as your body senses the presence of any injury or invader (入侵者), the innate immune system launches into action by producing tiny proteins called cytokines and chemokines. The cytokines reproduce almost immediately and start to attack the virus. This increase in immune cells creates an serious inflammation(炎症) throughout the body. But the worst is still to come. Meanwhile, the chemokines work with the adaptive immune system to help create T cells. These cells are a special type of white blood cell that works in a much more specific way: They find the influenza virus, identify what's special about it, and create something unique on their surface that finds and destroys similar invaders.

    Cassandra Feeley finds it hard to manage on her husband's income. So this year she did something more than a hobby. She planted vegetables in her yard. For her first garden, Ms. Feeley has put in 15 tomato plants, and five rows of a variety of vegetables. The family's old farm house has become a chicken house, its residents arriving next month. Last year, Ms. Rita Gartin kept a small garden. This year she has made it much larger because, she said, "The cost of everything is going up and I was looking to lose a few pounds too; so it's a win-win situation all around."

    They are among the growing number of Americans who, driven by higher living costs and a falling economy, have taken up vegetable gardening for the first time. Others have increased the size of their existing gardens. Seed companies and garden shops say that not since the 1970s has there been such an increase in interest in growing food at home. Now many gardens across the country have been sold out for several months. In Austin, Tex, some of the gardens have a three-year waiting list.

    George C Ball Jr. owner of a company, said sales of vegetable seeds and plants are up by 40%, over last year, double the average growth of last five years. Mr. Ball argues that some of the reasons have been building for the last few years. The big one is striking rise in the cost on food like bread and milk, together with the increases in the price of fruit and vegetables. Food prices have increase of higher oil price. People are driving less, taking fewer vacations, so there is more time to garden.

Research spanning several decades demonstrates that you are more likely to think the information that is repeated to be true than the information you hear only once. You usually assume that if people put in effort to repeat a statement, this reflects the truth of the statement. This tendency-also called the truth effect-is a bias （偏见） that can lead you to draw incorrect conclusions. 

To what degree are people aware of the truth effect? This question was addressed in a paper in the journal Cognition early this year. 

In the critical study in this paper, participants did two sessions. In one session, they read about a hypothetical （虚构的） study in which they were exposed to some statements and then were asked whether both statements they had heard before as well as these new statements were true. They were asked to predict the proportion （比例） of each statement that would be judged as true. They did this both as a prediction of other people's performance as well as a prediction of how they would do in this study. 

At another session a few days later, participants actually performed this study, reading a set of 20 statements in the hypothetical study again and then judging the truth of altogether 40 statements, half of which were from the hypothetical study and the other half of which were new. 

This study did replicate the well known truth effect. People were more likely to judge statements they had seen before as true than statements that were new. Two interesting findings emerged from the prediction. First, participants tended to underestimate the size of the truth effect for everyone. T hat is, while they did expect some difference in judgments between the statements seen before and those that were new, they thought this difference would be smaller than it actually was. Second, participants more significantly underpredicted the truth effect for themselves compared to that for other people. 

This study is particularly important in light of the amount of misinformation present in social media. Many people have the power to influence public opinion about important matters. Flooding social media feeds with misinformation will lead people to believe this information is true just because it is stated. Recognizing that we are all susceptible to this influence of repeated information should lead us to mistrust our intuition （直觉） about what is true and to look up important information prior to using it to make important judgments and decisions.
