@Justicar What kind of use?
I was considering the utility of female labor in contrast to male labor yesterday as well. Historically, females in non-elite classes took the division of labor that males left to them by virtue of their constitution being lesser than that of their male counterparts. Wives and daughters were nurses, bookkeepers, cooks, maids not because the males were doing the jobs they couldn't.
@Justicar I agree with you. My statement seems to be a generalization of the special case you're addressing.
