Thank a (yet another) perverted french king for that utter idiocy from not that long ago.

To put it simple: laying on your back while giving birth is going against every natural instinct of every mammal on the land and also against gravity, since, instead of letting gravity help you, you make sure the baby puts pressure on the pelvis, making it even harder to get it out of your god damn uterus.

Why doctors still do that is not clear to me! Isn't it a doctors job to do no motherfucking harm to their patients? You know, with that whole Hippocratic Oath and all?

Since not everybody on this planet can get pregnant or wants to get pregnant, I came up with an example for the better understanding on this subject:

Let's imagine, you have to take a really, really big dump. You're on the toilet and are already struggling with it for a while! Is your first god damn instinct to lay flat on your back and try to push it out like this? I bet it isn't because the first instinct I have is squatting!

And to all the mothers who should stumble over this and gave birth while laying on their back like a useless bug: your delivery could have been reduced by hours.
