There were some neatly-pressed explanations for this, none of which I would dispute.
Women have fuller, busier lives; they have better things to do with their time; they have woken up to the fact that you can now buy clothes that don't need ironing; and they have cottoned on to the fact that no one bothers to check if you've ironed the kids' socks, undies and pillow cases - least of all the kids.
As a recidivist ironer, I can't argue with this gender-based setting of the dial to zero and switching off at the plug.
I iron my shirts for work, and I iron the kids' school uniforms because I would like them to look presentable - at least at the start of the school day. In our house, I am the chairman of the board.
I am not alone among men on the shirt front. Many think it important to look smart for the office; women may be more concerned with looking attractive.
And ironing may be a well-creased metaphor for bigger things.
Men stuck in a routine/ritual that could be past its sell-by date; women already moving on. Men putting on a smooth appearance as they suffer the bumps and bruises of a career's rollercoaster ride; women, again, having better things to do with their time.
As always with this topic, I have entered a world of sweeping generalisations. But I think there's a grain of truth in there.
