Kara-Lynn: Hi, Bill. Can you tell me how it happened?
Bill: Sure. I was climbing the mountain in Nuremberg. Suddenly, the weather became really bad. There was lots of snow and we couldn't see anything. We got lossed. Well, we spent 4 days on the mountain. The temperature was 20 degrees below 0. We didn't have any equipment or food.
Kara-Lynn: So what happened? I guess somebody found you, right?
Bill: Yes. But we were very sick. I couldn't move my legs because of the cold. I spent 2 months in the hospital. The doctors removed my legs.
Kara-Lynn: Right, so you lost your legs, but you want to try your best to stay active.
Bill: That's right. In fact, I decided to make some new legs for myself. I realized that no one has to be physically disabled. We can use modern technology to help.
Kara-Lynn: And you built the new legs. Can you go mountain climbing again?
Bill: Yes, I can. In fact, these are better than climbing shoes. The spring design means they're much more powerful.
Bill tells Kara-Lynn his legs were removed because of a terrible accident in the mountain, but he built a new leg and now he can go mountain climbing again.
