I was watching a comedian/tv show the other day, i forget who it was, may be been Russel Howard (British Comic) talking about the top 5 most painful things (Child birth came 2nd, beaten by a kick to the nuts). One story he told, which i'm sceptical as to whether it's true or not but still makes me cringe is his friend dislocating his leg at the hip during football (or soccer, if you must). apparently a paramedic ran onto the pitch to pop it back into place, not knowing his testicle had slipped into the hip socket. I think you get the idea.
What also got me thinking was his point on how childbirth can't be that bad because from an evolutionary standpoint it makes no sense. Why make something necessary for the continuation of the species so fucking painful? If you look at most species of animals, they pop it out no problem. It could just be women making a big fuss over nothing. Obviously i'm not in a great position to comment and am not saying it's not painful, it's just a thought. But i do refuse to believe it's more painful than something not meant to happen, i.e Kidney stones, being shot, having your arm bitten off, standing on a plug etc.
