Young people in the United States do not have a strong understanding of the world and their place in it.

Two US-based groups, the Council on Foreign Relations and the National Geographic Society, conducted an online survey last year. They wanted to know what young people in American colleges knew about geography, U.S. foreign policy, recent international events, and economics.

The survey was given to over 1,200 Americans between the ages of 18 and 26 years. All of them presently attending, or having previously graduated from, a 2- or 4-year college or university.

The average test score, out of 75 total possible answers, was 55 percent. The study identifies a few important problems. For example, only 30 percent knew that the only part of the U.S. government that can declare war is Congress. Only 60% of those taking the survey could identify Brazil on a world map.

Part of the problem, argue the organizers of the survey, is the Internet. They say it is becoming harder to find high-quality information about world events amongst all the fake news and trivia which swamp the web. Forty-three percent of those questioned said they read about the news on Facebook.

Another problem is that most college courses do not require students to learn about international issues. If such information is not required, Richard Haass from the Council on Foreign Relations said, then the United States could have leaders like Gary Johnson. He was a recent presidential candidate who did not know about the Syrian city of Aleppo when a reporter asked him about it.

The survey results were not all bad. The young people also demonstrated a good understanding of climate change and renewable energy. And the majority of them said that international issues were becoming more important to them.

Haass says these findings suggest the need to find ways to get good information to students, both in school and online. To help, the Council on Foreign Relations is creating a new program called CFR Campus, designed to help build knowledge about global issues.

Our success, satisfaction and general happiness in life is not dependent on what happens to us but how we deal with it.

You will probably know from personal experience what a difference your attitude can make when, for example, you，re returning faulty goods or making a complaint. An open, polite and friendly approach，expecting a satisfactory result，normally results in one as people tend to respond with a similar attitude. If, however, you present an argument with an angry, accusing tone, expecting trouble, there is little doubt that this is what you’ll get!

Some people see the world through a filter of optimism and some through a filter of pessimism (悲观) which largely comes down to having a positive or negative (消极的) attitude. People who are suffering from a negative attitude primarily think that something can’t be done; they talk about problems, see all the difficulties, find fault with and criticize other people and focus on all the things they would like but haven’t got. On the contrary, people blessed with a positive attitude think that anything is possible. They look for ways to solve the problems, they see the good in everybody，and they are grateful for all the good things in their lives.

Whether suffering from or blessed with your attitude, this is not something that is put on us from the outside. We are very much responsible for our own attitude. We all start out with a “clean” board but this can get muddied by our experiences in life. As children we are made fun of and even get bullied (欺侮) and rejected, start to experience doubt and lose our self-confidence. If this continues into adulthood, it can result in a bad attitude in later life.

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.
