Why are Men Over-represented in the Pectus Excavatum Statistics

There are around three times more men whom have pectus excavatum than women. It is a statistically fact.

My main theory is (as I stated earlier) that pectus excavatum is caused by ergonomic reasons combined with genetic factors. The ergonomic main reason after birth is to lift the human heel with ordinary shoes (shoes with heels) so that they manipulates with the skeletal and muscular system in the human body. The human body is perfectly constructed for walking without shoes (it is a scientific fact).

What is the difference between men and women from an ergonomic perspective that is the big question here? And a little more detailed question is of course what is the difference when it comes to shoes?

I think the answer is that men are taller and have bigger feet in general. What effect will it have? The bigger feet, the bigger will the moment (Nm, newton metre) be when the feet are lifted up under the heels. This means that it is more likely that the body reacts by leaning backwards. And as my main theory goes, that is the devastating reaction that may lead to pe. What will the effect be if a person is very tall? The taller the person is the further away from the ergonomic balance line that person will go. This theory I have, is illustrated mathematically in the picture below.
