I spent about twenty minutes photographing this guy, switching between being fascinated one minute and cringing the next. And I guess the cringing must have been obvious because about ten minutes in he stopped, leaned over, and, in a slightly puzzled way asked me "Do they not do this to meat in your country?" And I guess they do, though maybe not quite on the same scale, but it's not something I'd normally watch.

And I do appreciate that it's a rather gruesome shot – it still makes me cringe – so my apologies to anyone who now wishes they hadn't seen it.
