Once I hit the "I could afford this" point I started researching Everest...read Into Thin Air, Dark Summit, No Shortcuts to the Top, etc., watched every documentary I could get my hands on, even talked with one of the climbers featured on the Discovery series that featured Russel Brice's company.
I've concluded that I'm not interested. I'm not interested in standing in line at the Second Step for hours while my body consumes itself and I burn through the scant amount of oxygen I have. I'm not interested in the very real risk that I may arrive back at Camp IV after a summit attempt to find my O2 and supplies stolen. I'm not interested in seeing the corpses, oxygen bottles, tents, and other detritus cluttering up the mountain.
I'm not condemning those who chose to go or those who help them get there, but I'm out: human behavior has made the idea of summiting Everest unappealing.
The couple years I lived in CO I managed to get a few done and really enjoyed the experience.
