Say what you will, what he did was beyond impressive. 52 is way too young, but when you do what only a handful out of 7 billion people can do you've probably lived a fuller life than most.
I can't imagine what it must be like to know that even the tiniest mistake is the only thing between life and certain death.
One of the stories linked to above mentioned that he was climbing with a shoulder injury.
