You know how, when your boss says, "Does anyone want to abseil down the Orbit in the Olympic Park on Friday?", you say something along the lines of, "No thanks, I'm busy that day/washing my hair/got too much work to do/all of the above"? Turns out, I don't. Turns out, my answer to that question is "Ooh yes, I'll do it, I'd love to. Me, pick me!"
