I just finished reading Chris Bonnington's account of his team getting to the summit of Annapurna via the South face, and I'd agree that it sounds grindingly hard, dangerous and unpleasant. There's no way I'd do it but then I will pay to bury myself riding a bike in mud for fun, which to others might sounds like their idea of hell.
I suppose if you have the goal the pain is worth it, but the risk of death is a whole other level with high altitude climbing. I cannot understand the mentality of people who leave a wife / husband and children at home to take their chances…
