Tim,
Finished watching the lot. Good film (seems to be largely extracted from the film) and certainly a testament to the guys determination. If I'm honest, that kind of stuff doesn't really inspire me, simply 'cos I believe it's more significant how we face life than how we face death and I'm certainly not a fan of "you have to face death to feel alive". Not to take anything away from the guys, but extreme sportsmen/women (and Alpine style up that is as about as extreme as you can get) are by the very nature of what they do, extremely self-serving and selfish for the most part.
I thought Simpson's involvement in "Free Tibet" was interesting but I can't work out how much they do on an ongoing basis since their online community seemed to die about 12 months ago.
Was trying to work out whether the book was worth reading but in searching around it looks like "Storms of Silence" would be more my kind of thing. Thanks for posting it though. Certainly interesting.
