Reinhold Messner: You did a good climb and you have the grade of difficulties because this is in the description. So you know, “These difficulties I can handle, I can manage.” But next time, you try to do a little bit more, a higher wall, a more difficult wall. And in the end — I went from the Alps to the Himalayas — especially because I lost my toes partly in the tragedy on Nanga Parbat, losing also my brother, and I was not able to climb anymore like before. Never ever after ’69 — this was my best year, ’68-’69, as a rock climber — I could approach the difficulties I did before. And losing this ability, I lost also interest and enthusiasm for this activity. So after a while of discussing with myself, I decided to expose myself to the high altitudes, to try to become a high-altitude climber. I was beginning by zero, learning from other ones, seeing how they handle it. And I changed the whole high-altitude alpinism.
