Example Input: Article: "No man is an island" is a well-known line from John Donne's Devotion. It was written more than three hundred years ago. Even now people still agree with him. No one can live a completely lonely life. Without other people, life will become empty and sad. We all need to have friends. For some of us, although making friends is not difficult, feeling shy, we may not want to make the first move. It is also difficult at times to keep the friends we already have. There are many books about friendship, but Dale Carnegie's How to Win Friends and Influence People, written in 1936, is the most famous. This "how to" book about getting along with other people became a best seller. It was later put into 28 languages. Dale Carnegie's advice seems to be simple, but can his advice help you? Do you need to change the way you act? Here is the list of advice from his book: Be friendly and polite. Always greet with a smile. Begin with "Excuse me" or "Would you please" when you want to ask somebody. Remember to say "Thank you" and try to be as helpful as you can. Go out of your way to be nice. Find some time to do special things for other people. Making some soup for a sick neighbour may seem like a little thing to you, but it will make your neighbor feel a lot better. Remember names. They say that the sweetest music to a person's ears is the sound of his or her own name. Be open-minded. Try to understand other people's ways and ideas and learn something from them. Listen patiently. When someone is talking to you, look at him or her, listen carefully and say something when necessary.

Example Input: Article: More and more people are taking their iPads to bed with them to surf the web, check facebook or send e-mails before switching off the light. But researchers are warning that the blue light their screens give off can stop users getting a good night's sleep. That is because this type of light is similar to daylight, convincing the brain that it is still daytime. Blue light prevents the production of a brain chemical called melatonin, which helps us fall asleep. By contrast, light which is more orange or red does not prevent melatonin production, perhaps because our brains recognize it as a cue that the day ends. Scientists have known for years that staring at screens late in the evening can affect sleep ---- they are television screens, computer screens or mobile phone screens. However, because mobiles and iPads are by nature portable ---- not to say addictive ---- more people are taking them into the bedroom. Users also tend to hold them much closer to their eyes than a computer or television screen. Researchers are warning that looking at iPad displays for more than two hours leads to lower natural melatonin levels as the devices give off blue light. They say, "Turning off the devices at night is the final solution. But if you have to use these devices at night, dim the display to cut down irritation of the eyes and limit the time you spend on them before bed." They wrote in the journal Applied Ergonomics that iPad makers should adjust the spectral power distribution of the devices so that they affect the sleep patterns of users less. It is not just a good night's sleep that could be harmed by too much late night screen time. Researchers know that long-term harm to sleep patterns can lead to an increased risk of obesity and even cancers.
