I don't think that we are able to specify a proportion, Chair. I would indicate, however, that demographics are without question a factor. Age, unfortunately, often carries with it the triggering of disability, so that is definitely a factor, but I do not believe that we have the capacity—I'm not sure it exists anywhere, frankly—to be precise about causality as far as the quantity is concerned. But unquestionably it is a factor.
