Years ago, I think it was back in college, I opined about a hypothesis I had developed to some derision by a friend of mine. I get these hypotheses from time to time and they're not the kind of thing I have any way to test, but they're just examples of free floating thoughts. It's just idle mental pattern-making, looking for connections where none (as far as I am aware) have been thought to exist.
For example, I believe that men should occasionally urinate in their yards to prevent burglary.
Stay with me for a second.
It has been conclusively demonstrated that our brains are hardwired to register odors that are actually too faint to be noticed consciously. The brain actually has a sort of sensory collection function and at the same time a sensory censorship function or else you'd be all raw nerves constantly having to notice your too tight shoe and someone's gum and the smell of the carpet and the faint sound of things far away.
The brain filters much of this out, but sometimes you suddenly become aware of something that your brain has been noting for quite some time. For instance, that prickly feeling that someone is behind you might actually be your brain taking the smell of the person into account but not telling you about it until it's almost too late.
And so, in keeping with my hypothesis, burglars' brains would note the urine markers of a male on the property and perhaps get "a feeling" to try a different place to rob.
Just one of the many ways that my mind sometimes works.
Well, the hypothesis I mentioned to my friend was that you could judge a woman's fertility based on the sway of her hips. I postulated that a greater amount of hip-shake indicated a higher rate of fertility because the motion of the hips acted as a cradling mechanism for babies. This was nature's way of signaling a good breeder, letting potential mates know that a female's body was ideally suited for the bearing of children.
It's not exactly on the money, the correlation between female orgasm and fertility still hotly debated, but this recent scientific study suggests I might have been on to something.
