Sorry I was not talking about physical discomfort but all negative aspects of a job. Men have a greater incentive to seek high pay & status at the price of longer commute / longer hours.

Women do not in my experience value pay as highly and consider the (non-monetary) costs more carefully than men.

The job someone earns at the end isn't discomforting, but getting to the point where you deserve that job based on merit and acquired skills is more discomforting. A four year engineering degree is far more "discomforting" than a four year sociology degree.
