TIL a muscle is the sound in your ear when you tense your muscle

Voluntary control

Contracting muscles produce vibration and sound^[2].
Slow twitch fibers produce 10 to 30 contractions per second (equivalent
to 10 to 30 Hz sound frequency). Fast twitch fibers produce 30 to 70
contractions per second (equivalent to 30 to 70 Hz sound frequency)^[3].
The vibration can be witnessed and felt by highly tensing one's
muscles, as when making a firm fist. The sound can be heard by pressing a
highly tensed muscle against the ear, again a firm fist is a good
example. The sound is usually described as a rumbling sound. Some
individuals can voluntarily produce this rumbling sound by contracting
the tensor tympani muscle of the middle ear. The rumbling sound can also be heard when the neck or jaw muscles are highly tensed.

Jay you know if you fill your brain up with all kinds of miscellaneous stuff your going to run out of room up there. [][]

There is also a muscle in your butt that more or less does the same thing at the same speed, right before you get in an accident or just after you do something really dumb. []

I had to take one about 30 years ago for a company I worked for when a bunch of stuff came up missing. I didn't care, I didn't have anything to do with it and had no idea who did. I guess I passed, no one was fired, I really didn't care I was Innocent .
