W: Hi. Phil. can you tell me how it happened?
M: Sure: I was mountain climbing in New Hampshire in 1982. Suddenly the weather became really bad. There was a lot of snow and we couldn’t see anything. We got lost. Well, we spent four days on the mountain. The temperature was -20℃. We didn’t have any equipment or food.
W: So what happened? I guess someone found you, right?
M: Yes. but we were very sick. I couldn’t move my legs because of the cold. months in the hospital. The doctors removed my legs.
W: Right. So you lost your legs, but you want to try your best to stay active.
M: That’s right. In fact, I decided to make some new legs for myself. I realize that no one has to be physically disabled; We can use modern technology to help us.
W: And you built these great new legs. Can you go mountain climbing again?
M: Yes, I can. In fact, these are better than climbing shoes, The spring de- sign means they are much more, powerful.
