That's the fun of this thread- if you didn't have loved ones to worry about, and could afford the time and money was no issue... For most of us, it's pure fantasty. Being married I would never go, besides the fact that I could never affrord it. Interstingly enough, I posed this question to my husband and he said he'd go too...
Anyway, just because someone has a family and has the cash, doesn't mean they can't make the choice to go. I don't think it's a matter of thinking that you can beat the mountain and make it out alive, or believing that you will make all of the right decisions, "it won't happen to me". That might border on delusional, since it's proven fact that bad things can and do happen to anyone up there. Accepting the risk, knowing that something bad might happen, and being prepared to deal with the consiquences, even if it means dying doesn't make you delusional, stupid maybe. Maybe it is self centered or selfish, which is why in the first post it was stated that there would be no family issues. It's about overcoming challenge, risk and completing goals, which I guess is ultimately a very personal and self-centered thing.
