Nice riposte Neil ;-}
At this stage I'd give someone a strapping for nix!
No TL, not me. Tho cashed up fit folk in their 50s have been guided to summit Everest without any real mountaineering or high altitude experience.
Why do climbers do it? The intensity of the experience - narrows existence down to just effort and survival, banishes trivialities. The views on the way. But there's usually no jubilation at the summit: many climbers are mentally sub par (hypoxic) by then, can't spend much time there and are not even half way cos going down is harder than getting up.
PS, a Sherpa holds the record for the most ascents. Most Sherpas do it as a living; to summit will boost the demand for their services. That said, Tenzing Norgay, who summitted with Hilary in 1953, was as taken with the splendour of the mountains as many western climbers.
