There's a t-shirt I'm rather fond of... it has an illustration of a piper, and around him is written "Genetically pre-disposed to the sound of the pipes." I think there may be some truth in that, though it can be argued whether it's nature or nurture -- most of us with Scots heritage were raised hearing the pipes, at least occasionally. I, for instance, had an alblum by the "Pipes and Drums of Her Majesty's Black Watch" or something like that, as a kid, and listened to it near endlessly.
