What is the man mainly talking about?

W: Why did you start rock climbing?
M: Because the rocks were there. At 20 I spent most of my time rock climbing. At 25 I went for the first time to the Himalayas and climbed Nanga Parbat, one of the highest faces in the world.
W: What was your basic interest and motivation in climbing high mountains like the Himalayas?
M: It was only a new dimension for me. I was the first to break this system with the Alpine style, which meant, no fixed ropes, no high altitude camps, and no oxygen.
W: You don’t want to bring your equipment to the mountains?
M: Exactly. Otherwise you loose the exposure. I know that all over the world climbers bring 100kg of equipment for communications. For them, the most important thing is to send information to their friends every day, and maybe a television station. It’s not my way. I like to be where others are not going and no one knows what I’m doing and I don’t know if I’m coming back.
W: So climbing was never a competition.
M: No. Climbing was never even a record. It was a personal experience. Climbing has to do with exposure, endurance, instinct, with knowledge of mountains, knowledge about your own nature. It’s interesting to see what happens when a man and a mountain meet. In our inner soul something happens.
