Ow ow ow ow.

Want to know if your ears (at least) belong to an old fart or not? Go to this site and play the famous Mosquito tone. (Once you get to the actual site, it says "Click here" but that's not where you click; you click on the "Play" triangle on the little sound player. I hate ambiguous user interfaces.) If you can hear it, your ears are still as spry as those of a teenager. If you can't, maybe it's time to look into getting that recliner you always wanted. Me, I heard it very, very painfully clearly.

Of course, age is only a state of mind, and has nothing to do with what frequencies you can detect with the naked ear. What the — oh, for — hey, you kids, get off my lawn!
