Erm, not necessarily cerebral. Just need to have a good vocabulary of choice naughty words.
I'm practicing said vocabulary for when I tear into Sophie's carbs this winter. Of course I'm bringing it on myself because she is running very well; I just want to poke around in there because it's one of the few things I have never done before. Fuel injected bikes spoil you.
