I guess I would like a little bit of feedback from the witnesses. I heard Dr. Urbain say he was first concerned about problems with Canada's system for cancer about six years ago, when he first started his practice in Canada. I heard Dr. Lamoureux mention about three years ago. When did you, as doctors who specialize in nuclear medicine, begin to become concerned first of all about the safety of supply of the world's nuclear medicine system?
Looking at it from my eyes as a layman, I see we have 50-year-old reactors, and 25, 30, 35 years in, I would have thought they would have started to be concerned. So three or six years ago seems to me to be a little bit short. Maybe we should have been concerned about this 10 or 15 years ago. Would that be an accurate viewpoint?
