I try to do a lot more with one hand only, as if I was on a steep part of a route, hanging on with the other hand. I've developed a dextrous method of eating a bag of crisps with one hand.
But as far as boring work shit goes, I think climbing's excellent for organisation, concentration, following instructions clearly, withstanding stress, the ability to absorb limitless quantities of pointless jargon, and dynamic risk assessment (i.e. not doing the paper work).
