I think many of the women who got science and engineering degrees, in either natural and applied sciences, probably started working in the industry in which they have their degree, but gradually felt that they were not comfortable there, that they were not progressing, that they wanted to move to something else, so that 29% largely reflects those people who have moved from the industry in which they were initially educated into something different. That's a concern.
