The spirit of adventure lad - to test yourself both physically and mentally in the most extreme of conditions. Unless you've actually put yourself through the torture and torment, of a big climb, it's hard to explain exactly what it feels like to summit.
It is the most amazing feeling, totally indescribable! total elation/tears of joy/fear of getting back down safe/mental and physical exhaustion. However I do take your point about risk, now I've got kids the really big, dangerous climbs that were once my forte, are consigned to memory only, I'm not stupid.
This story concerns me because it involved a climber who died as part of a commercial expedition, these expeditions charge a small fortune for the chance of summiting an 8000m peak. Usually the offer is taken up by climbers who have no right to be anywhere near a big nasty 8000m mountain. However still they come and still they die on the slopes of Everest/K2/etc...etc
I only climb with people I know and trust, I would never consider setting foot on a mountain with someone I don't know or someone I had never climbed with before - its madness
