　　Most young people enjoy physical activities, walking, cycling, football, or mountaineering.
　　These who have a passion 26 climbing high and difficult mountains are often 27 with astonishment. Why are men and women 28 to suffer cold and hardship, and to 29 on high mountains? This astonishment is caused, probably, by the difference between mountaineering and other forms of activities 30 which men give their leisure.
　　There are no man-made rules, as there are for 31 as golf and football. There are, of course, rules of different kinds which it would be dangerous to 32 , but it is this freedom from man-made rules 33 makes mountaineering attractive to many people. Those who climb mountains are free to their own 34 .
　　If we 35 mountaineering with other more familiar sports, we might think that one big difference is 36 mountaineering is not a “team work”. However, it is only our misunderstanding. There are, in fact, no :matches” 37 “teams” of climbers, but when climbers are on a rock face linked by a rope on which their lives may 38 , obviously, there is teamwork.
　　A mountain climber knows that he may have to fight with natural 39 that ate stronger and more powerful than man. His sport requires high mental and 40 qualities.
　　A mountain climber 41 to improve on skill year after year. A skier is probably past his best by the age of thirty, and most international tennis champions 42 in their early twenties. But it is not 43 for men of fifty or sixty to climb the highest mountains in the Alps. They may take more 44 than younger men, but they probably climb more skill and less 45 of effort, and they certainly experience equal enjoyment.
