Certainly, in those days. I think a lot of the modern mountaineers, with their very good technical equipment and their very accomplished techniques, can climb more naturally and easily than we did in our day. But, of course, we had one problem that the modern mountaineer doesn’t have. That is, this psychological barrier. We really didn’t know whether it was humanly possible to reach the top of Mt. Everest. And even using oxygen as we were, if we did get to the top, we weren’t at all sure whether we wouldn’t drop dead or something of that nature. All the physiologists had warned us that the altitude at the summit of Everest was a very marginal altitude and might be extremely dangerous. So, one had this feeling in your mind all the time that maybe you were pushing things a bit beyond what humans were meant to do and you couldn’t ignore that feeling. But, because of strong motivation, you keep plugging on and you seem to be going okay and nothing seems to be going wrong, so you persist. And we persisted, of course, and ultimately, set foot on the summit.
