According to this story on John Baird, Baird has been a vegetarian for the past 10 years.
Having been an "on again/off again" vegetarian since I was 16, this appeals greatly to me. It puts Baird into a whole new light as a reflective, well-purposed man. I no longer see him as Harper's pitbull. In fact I see him more like a border-collie - intelligent but with a lot of energy.
