That’s true. But my point was, that if you’ve got the money and your body holds up it’s “doable” for the most part.
But from what I’ve read, K2 is absolutely brutal even compared to Everest.
The nasty exposure on Everest Southwest Col route begins at 23-25,000 feet. The exposure on K2 begins at the very beginning, and never stops. That's what I've read.
I forgot to mention, Mt. McKinley (Denali) in Alaska also has a brutal rep for a couple reasons.
I'll just cut this from Wikipedia:
Mount McKinley has a larger bulk and rise than Mount Everest. Even though the summit of Everest is about 9,000 feet (2,700 m) higher as measured from sea level, its base sits on the Tibetan Plateau at about 17,000 feet (5,200 m), giving it a real vertical rise of little more than 12,000 feet (3,700 m). The base of Mount McKinley is roughly a 2,000 foot plateau, giving it an actual rise of 18,000 feet (5,500 m).
The mountain is also characterized by extremely cold weather, and by an unusually severe risk of altitude illness for climbers, due to not only its high elevation but also its high latitude.[2] At the equator, a mountain as high as Mount McKinley would have 47% as much oxygen available on its summit as there is at sea level,[3] but because of its latitude, the pressure on the summit of McKinley is even lower.[4
