A doctor has recently climbed Mt. Everest, and he was "shocked" when he knew that the number of altitude-related illness and the climbers’ ignorance about it.
"From being there, I saw there were a lot of people with considerable mountaineering experience, but who were fairly naive in some ways about the extreme altitudes they were going to face."
"In my view, climbers are not climbing beyond their ability but instead beyond their altitude ability. Unfortunately, it is difficult to get experience of what it is like climbing above Camp 3 (8,300 metres) without climbing Everest. Climbers invariably do not know what their ability above 8,300 metres is going to be like. The longer you stay up there, in the death zone, the greater the chance you have of dying."
While most deaths are caused by injuries and exhaustion, there is also a large proportion of climbers who die from altitude related illness. High altitude cerebral oedema (HACE) and high altitude pulmonary oedema (HAPE) are both forms of altitude sickness which cause a potentially fatal build up of fluid in the brain or lungs.

That's my point. Climb every mountain? I say choose the mountains you climb, and do not do something out of some blind urge. Know the facts first. It can save your life.
