I have always wondered if girls knowledge that they're likely to want a child some day factors into this. That is it gives them a timeframe (between late 20's and late 30's say) that they kinda know they want to be in a position to have a child and working back from that they need to get an education and begin a career. It gives them almost a timescale to plan against and boys have nothing similar in the biological sense. I genuinely have no clue if it actually holds any weight, just something I've always been curious about.
