Yup, sounds completely reasonable.
Hey, how come so many more women become doctors now? High stress job, takes a long time, I don't think it's any more "attractive" then being a nurse.
I'm gonna go ahead and say that this line of thinking is sexist. I'm not trying to attack you I just think it needs to be said because I think it's actively harmful. It ignores any other reasons behind the gap, and it's a terrible line of thinking for anyone who manages women. "I don't know if I should give her this role, women aren't really suited for leadership".
