Gopnik's Gender Curves
The male curve is an abrupt rise followed by an equally abrupt fall. The female curve is a slow rise to an extended asymptote. The areas under the curves are roughly equal. These curves apply to all activities at all time scales (e.g. attention to TV programs, romantic love, career scientific productivity).
