Помогите пожалуйста,нужен краткий пересказ текста.
You will probably laugh when I tell you that my interest in body language was sparked by a favourite professor of mine at university. He mentioned 'Pinocchio Syndrome' to me one wintry morning after claiming that I always rubbed my nose when giving excuses for being late to his lectures. Apparently, when someone tells a lie, the person's blood rushes to the nose and the extra blood makes it itchy. So if you think someone is not being entirely honest with you, perhaps like my professor you should watch to see if they scratch their nose! This little example of non-verbal communication inspired me to become a body language expert.
Now, I earn my living by training people in non-verbal communication. Knowing when someone is lying and knowing how to convince people you're telling the truth are two of the most important skills you'll ever learn. For example, lawyers build their reputation on their deductive skills when cross-examining in court, while politicians need to rely on their powers of persuasion to gain support.
Take the eyes, for example. If I told you a lie, you would probably expect me to look away rather than look you full in the face. However, this is not, as commonly thought, the sure sign of a lie, but the reflexive movements we make when we are trying to remember something. Because of this, glancing away is not as easy to interpret as you might believe. A good liar is not searching his memory for the truth, so he can quite easily look you straight in the eyes as he speaks to make the lie more convincing. Here's a tip, though. Watch the pupil of the eye; does it change size? If it gets bigger, this is probably an involuntary sign that something is being hidden.
Body language is something that the majority of us cannot control; it's what escapes when we're concentrating on something else. I might think I'm creating a good impression because my voice is strong and steady and my speech is clear, but the sweat pouring off my forehead and my constantly moving feet say otherwise.
Business clients are constantly in need of my services and I try to improve their confidence in themselves by teaching them about body language. I give advice about handshakes, which should always be firm and steady, and I teach the importance of personal space, explaining that people who live in warm climates stand a lot closer to one another than people in cooler climates. They may seem like minor matters, but these codes of behaviour can be the key to making or breaking a business deal.
My working life gives me a great deal of satisfaction. I feel that I'm providing a public sen/ice, but it is a sen/ice that has had its downside. Whenever I meet someone new and I tell them what I do for a living, they immediately put their guard up and they're no longer relaxed. They quite literally freeze in the attempt to hide all the signals that they assume I'm reading. It makes life difficult at times, but I consider it a small price to pay for a job I enjoy so much.-
