The world has become so complex that we’ve lost confidence in our ability to understand and deal with it. But common sense is useful now as it ever was. No amount of expertise (专家意见) substitutes for a detailed knowledge of a person or a situation by oneself. At times you just have to trust your own judgment. It almost cost me my life to learn that. I was reading a book one day, idly scratching the back of my head, when I noticed that, in one particular spot, the scratching echoed (回声) inside my head like fingernails on an empty cardboard box, I rushed off to my doctor. “Got a hole in your head, have you?” he teased. “It’s nothing – just one of those little head skin nerves sounding off.”

Two years and four doctors later, I was still being told it was nothing. To the fifth doctor, I said, almost in desperation, “But I live in its body. I know something’s different.”

“If you won’t take my word for it, I’ll take an X – ray and prove it to you,” he said. Well, there it was, of course, the tumor (肿瘤) that had made a hole as big as an eye socket in the back of my skull. After the operation, a young doctor paused by my bed. “It’s a good thing you’re so smart,” he said. “Most patients die of these tumors because we don’t know they’re there until it is too late.”

I’m really not so smart. And I’m too  easily – controlled in the face of authority. I should have been more aggressive with those first four doctors. It’s hard to question opinions delivered with absolute certainty. Experts always sound so sure. Nevile Chamberlain, the British prime minister, was positive, just before the start of World War II, that there would be “peace for our time.” Producer Irving Thalberg did not hesitate to advise Louis B. Mayer against buying the rights to Gone With the Wind because “no Civil War picture ever made a nickel.” Even Abraham Lincoln surely believed it when he said in his Gettysburg Address: “The world will little note, nor long remember, what we say here…”

We should not, therefore, be frightened by experts. When it’s an area we really know about – our bodies, our families, our houses – let’s listen to what the experts say, then make up our own minds.

What is your favorite color? Do you like yellow, orange, or red? If you do, you must be an optimist, a leader. an active person who enjoys life, people and excitement. Do you prefer greys and blues? Then you are probably quiet, shy, and you would rather follow than lead. You tend to be a pessimist. At least, this is what psychologists tell us, and they should know, because they have been seriously studying the meaning of colours preference, as well as the effect that colours have on human beings. They tells us, among other facts, that we do not choose our favourite clour as we grow up----we are born with our preferences. If you happen to love brown, you did so as soon as you opened your eyes, or at least as soon as you could see clearly.

Colours do influence our moods----there is no doubt about it .A yellow room makes most people feel more cheerful and more relaxed than a dark green one; and a red dress brings warmth and cheer to the saddest winter day. On the other hand ,black is depressing. A black bridge over the Thames River, near London, used to be the scene of more suicides than any other bridge in the area ----until it was repainted green. The number of suicide attempts immediately fell sharply ;perhaps it would have fallen even more if the bridge had been done in pink or baby blue.

Light and bright colours make people not only happier but more active. It is an established fact that factory workers work better, harder ,and have fewer accidents when their machines are painted orange rather than black or gray.
