But new research suggests that putting on a fake smile can worsen people's mood and even lower work efficiency. Lead researcher Brent Scott with other researchers studied a group of bus drivers for two weeks. They tried to find out what happened when the drivers were involved in "surface acting" or fake smiling, and the opposite, "deep acting" which means people put on real smiles by recalling pleasant memories or thinking about their current situation more positively. The results showed that on days when drivers were forced to smile, they felt depressed and didn't want to work. On days when they smiled due to positive thoughts, their mood improved a lot as well as their work efficiency. The research goes against the popular belief among companies that employees should be cheerful to customers at all times. They include employees of shops, banks, call center workers and others who have face-to-face contact with members of the public. "Smiling for the sake of smiling can lead to emotional exhaustion and coldness, and that's bad for the organization," Scott told the Daily Mail. The study also showed that women were harmed more by fake smiling than men. Their mood and work performance both worsened more. But they were helped more by deep acting -- their mood became better and they worked more efficiently. However, while deep acting seemed to improve mood in the short term, Scott says it's not a long-term solution for unhappiness. "There have been some suggestions that if you do this over a long period that you start to feel inauthentic ," Scott said. "You may be trying to cultivate positive emotions, but at the end of the day you may not feel like yourself anymore."

Thomas became fascinated by O'Brien's theory that anyone can improve their memory by using specialized techniques.These techniques involve linking everything to familiar people or objects. "If you want to remember a phone number for example, you have to give the numbers life.Sometimes I associate a number with a person.Number 10 for me is always the Prime Minister (who lives at number 10 Downing Street) ," explained David.If David is trying to remember facts he also links them to an image."For instance, if I was trying to memorize the name 'Tom Cruise' , I would think of his film Top Cun, and that leads me to images of guns and cruise missiles." is soon going to appear on TV's Record Breakers, and this week he is teaching memory training and speed - writing at Huddersfield University.His fees are PS600 a day.He is sure that the future holds a lot more for him than a job as a fire - fighter.

Read the following article and select the best answer. Article: When you are at odds with someone close to you, the One-Minute Drill can show you how to express your feelings effectively - and how to listen more skillfully. All it requires is two individuals who are committed to improving their relationship. Set aside at least ten minutes, and then sit facing each other. Decide who will be the Talker and who will be the Listener. It makes no difference, because later you will change roles. How to perform the One-Minute Drill For approximately 30 seconds, the Talker can say anything he or she wants. Your job will be to express your thoughts and feelings. You can discuss problems you've had a hard time talking about. Remember to limit yourself to about 30 seconds. When the Talker finishes, the Listener will summarize what the Talker just said, as well as how the Talker was feeling inside, as accurately as possible. The Talker now gives the Listener a grade between 0 and 100 per cent to indicate how accurate the summary was. If the rating is 95 per cent or more, you can change roles; the new Talker can continue with the same topic or move on to something entirely new. However, if the grade is below 95 per cent, the Talker should point out what the Listener missed or got wrong, and repeat the process until the overall rating is 95 per cent or more. Then you can change roles and repeat the exercise for as long as you both like. How it works Thirty seconds of emotionally charged information is sufficiently challenging for anyone. Express your feelings in strong, clear, direct language, but as your partner will be listening attentively, you won't need to shout, exaggerate or put your partner down. The Listener should sit and listen respectfully without interrupting. Look into your partner's eyes, but avoid using negative body language. If you like, take a few notes. So the Talker might say: "When I come home from work, I feel tired and I need some quiet time. But you tell me I'm supposed to spend time with the kids. This makes me feel frustrated. I work hard and I'm exhausted at...
