Perfect.
I'll start by saying that actually, interestingly enough, the MS Society of Canada funds a large research program, and obviously one of the targets we want to support is looking at actually what triggers this disease.
I think it was Dr. Sellah who asked the question about looking at CCSVI in children. Even before that, we'd been funding research, by Dr. Brenda Banwell at the Hospital for Sick Children, looking at MS in children; it's rare, but it does occur. That actually provides perhaps some insight into what might trigger that disease. If someone develops MS at the age of three or five or eight, then their life experiences are.... It's far less complicated than looking at someone who develops the disease at 30.
So yes, there's certainly work on that. It's a complex disease. It's probably a combination of genetics and environment and various other exposures.
I can assure you that on the international level, certainly with MS and I suspect with other neurological conditions, there's a lot of international collaboration, because we certainly don't want to reinvent the wheel.
