"Something happens in the middle when women are in their 30s, and we can start with an array of things that happen, whether it is - you hope this doesn't exist any longer - but overt discrimination; whether it's subtle gender discrimination, which absolutely does exist among men and women; whether it's the fact that it gets hard to juggle at that point children, housework, etc. But people still have to go home and cook the dinner and clean the dishes and get the beds made and so on. And so, for a whole bunch of reasons, women tend to fall out in their 30s still today."
