I've come across many interesting things about ears lately. So listen up (hahahahaah!) and I'll tell you about them.
First, there's this device called the Mosquito that supposedly creates an annoying sound that only teenagers can hear. Its purpose is to "chase away those annoying teenagers!!!" (direct quote from the site). This is just wrong on so many levels. First of all, I'm sure it's not only teens who will hear it. I can still hear the high-pitched squeal of CRT televisions that most people are oblivious to. If it's anything like that, my well-beyond-teenaged ears will pick up on it. But worse is the blatant discrimination this device embodies. Calling an entire group of people "annoying" and creating a device that hurts them is so obviously evil that I'm surprised they're allowed to sell this. It's no better than putting steep steps in front of your store, so those annoying frail old ladies can't get in. Or a scary dog that only barks at those annoying black people.
The second ear story is Do Earlobes Have a Purpose? If you're too lazy to click, the article basically says "no, they have no purpose." They're an "evolutionary hiccup". I don't find the answer entirely satisfying...did they ever have a purpose? Why would they show up in the first place? Maybe they are sexual displays, there to be pierced to attract mates. This guy probably gets all the ladies:
Or maybe lobes used to help wiggle our ears into a better position to hear with. This leads to the last story: Noisy Wiggling Ears Explained. Many people can wiggle their ears (I can), and the article goes into how there is a part of the brain dedicated to this, and how other muscles (e.g. eye muscles) are involved in wiggling. What I didn't know is that the human ear can also produce noise. It can make little clicks...though it's unclear if this is at all related to wiggling. The weirdest thing, though, is that these clicks are loudest in heterosexual women, and less loud in bi or homosexual women (and all men just suck at ear clicks).
So remember ladies, if you "choose" to become homosexual, it may affect your ability to make noise with your ears. Oh wait, that makes no sense. It's probably actually some common brain structure that controls both ear clicking and sexual preference. Since we don't choose the structure of our brains, this is even more evidence to the support the obvious conclusion that sexual preference is not a choice (I only mention this because I blabbed about the topic a few days ago).
