M: Look at all the equipment here. They must be used for some kind of sport.
W: You are right. They are for climbing mountains. Have you ever tried that before?
M: No, never, have you?
W: Almost for five years.
M: Five years? Wow! Isn’t it a bit dangerous? I heard that a 21-year-old college student lost his life when climbing the cliff the other day.
W: Yes, it does happen from time to time, most often by people who just try when they are not yet ready for any risk.
M: Are there any climbing clubs for freshmen to join?
W: Yes, for sure. But you need time to pick out the best one. Nowadays, too many of these climbing clubs are too eager to initiate trips without checking properly the skill levels of the climbers.
M: Well, as a veteran, what experience do you think you can share with others?
W: Well, climbing success is considered by most to be almost 100 percent dependent on fitness and natural ability. But in reality, climbing is a much more subtle and complicated skill that needs not just fitness, but strategy and psychology.
M: That’s interesting to hear.
W: Over the years, I’ve picked up numerous tricks and techniques that have allowed me to occasionally beat a stronger competitor. At the grass-roots level, it is possible to just outride your opponents, but as you get into the higher categories and the gap in ability narrows, strategy becomes increasingly important.
M: Well, Katrina, thanks for your kind suggestion.
W: My pleasure.
