A mountain climber continues to improve in skill year after year. A skier is probably past his best by the age of thirty, and most international tennis champions are in their early twenties. ______ They may take more time than younger men, but they probably climb with more skill and less waste of effort, and they certainly experience equal enjoyment.

D. Those who climb mountains are free to use their own methods.
E. But it is no unusual for a man of fifty or sixty to climb the highest mountains in the Alps.
F. If we compare mountaineering and other more familiar sports, we might think that one big difference is that mountaineering is not a "team game".
