In reply to aln:
I'm not sure it was a point that needed proving; it is a shame that the nature of Everest publicity these days often means a particular angle for the press, rather than just going out and enjoying the challenge. Presumably we, the public, have ended up collectively 'buying in' to this attitude whilst we, as climbers, recognise it as potentially hazardous. Projecting your personal achievements or desires onto a cause alters the nature of the relationship IMO.
That's not to say I wouldn't like the axis of global food consumption to move away from poor quality cheap meat for many reasons, just that I'm not sure that an individual's achievements on Everest is a very effective way of going about it.
If people are wondering if vegans can be fit there are plenty of vegans with considerable power and endurance out there... e.g. Ifor and Alun Powell managed ok - didn't they win the Elite class in the LAMM a few years running, outside of their mountaineering adventures?
