　　　 Anxiety is the appropriate emotion when the immediate personal terror-of a volcano, an arrow, a stab(刺伤)in the back and other disasters, all directed against one’s self-disappears.

　　　 The kind of world that produces anxiety is actually a world of relative safety, a world in which no one feels that he himself is facing sudden death. The anxiety exists as an uneasy state of mind, in which one has a feeling that something unspecified and indeterminable may go wrong. If the world seems to be going well, this produces anxiety-for good times may end. If the world is going badly-it may get worse. Anxiety tends to be without focus; the anxious person doesn’ t know whether to blame himself or other people. He isn’t sure whether it is the current year of the administration or a change in climate or the atom bomb that is to blame for this undefined sense of unease.

　　　 It is clear that we have developed a society which depends on having the right amount of anxiety to make it work…While we agree that too much anxiety is harmful to mental health, we have come to rely on anxiety to push us into seeing a doctor about a symptom which may indicate cancer, into checking up on that old life-insurance policy which may have out-of-date provisions in it, into having a conference with Billy’s teacher even though his report card looks all right.

　　　 People who are anxious enough keep their car insurance up, have the brakes checked, don’t take a second drink when they have to drive. People who are too anxious either refuse to go into cars at all-and so complicate the ordinary course of life-or drive so tensely and carefully that they help cause accidents. People who aren’t anxious enough take chance after chance, which increases the terrible accidents of the roads.

　　　 Having reached the highest point of our route according to plan, we discovered something the map had not told us. It was impossible to climb down into the Kingo valley. The river lay deep between mountain sides that were almost vertical(垂直).We couldn’t find any animal tracks, which usually show the best way across country, and the slopes were covered so thickly with bushes that we could not see the nature of the ground. We had somehow to break through to the river which would give us our direction out of the mountains into the inhabited lowlands.

　　　 Our guide cut a narrow path through the bushes with his long knife and we followed in single file. Progress was slow. Then, when we thought we had really reached the river, we found ourselves instead on the edge of a cliff with a straight drop of 1,000 feet to the water below. We climbed back up the slope and began to look for another way down. We climbed slipped, sweated and scratched our hands to pieces and finally arrived at the river. Happily we came downhill along its bank without having to cut our way. However, after a few miles the river entered a steep-sided gap between rocks and suddenly dropped thirty-five feet over a waterfall. There was no path alongside it and no way round it.

　　　 Then one of the guides saw a way of overcoming the difficulty. There was a fallen tree lying upside down over the waterfall with its leafy top resting on the opposite bank below the falls. Without hesitation he climbed down the slippery trunk to show us how easy it was. Having got to the fork of the tree, he moved hand over hand along a branch for four or five feet with his legs hanging in space, then he dropped onto the flat bank the other side, throwing his arms in the air like a footballer who has scored goal, and cheerfully waving us on.
