 Well, I mean, it's always been a concern at the university and engineering, there are never enough women in there. Chemical engineering seemed to have resolved that, there were far more it seemed. Chemical engineering, for example, were mechanical. I know you're asking specifically about mining and metallurgical engineering, but my sense is that there's always been quite a number. One of the first papers I wrote was with Olga Makrychenko. I don't know where she is now, but we did some work on grinding and mineral distributions and grinding circuits. I remember her very well. I don't think there were any other lady, girl students in the class at the time. But if you look at the progress over the years, there's always been women in the group. Certainly the research group has always been. I think right now there's probably 40% are women. And the only graduate program has certainly had a steady number of women in the business. So I think mining and metallurgy might be doing a little better than some of the other engineering disciplines. Chemical engineering being the notable exception. So I don't have statistics on that. It's just when I look around. There's been a steady number of women in the graduate program. Certainly in the graduate program that was always true.
