This is my time to shine, my body is full of useless, I can:
gleek intentionally (saving people a search: it’s causing the salivary glands under your tongue to shoot saliva, people often do it unintentionally when yawning)
open my jaw wide enough that it goes out of socket, and twofer I can then move it side to side and produce a loud popping noise
bend my thumb down to my wrist
cause my heart rate to spike for short periods even when at rest
You know that feeling you get when you listen to really awesome music and your hair stands on end and your skin has like an electric tingle all the way up and down? I can do that feeling at will. It's called 'voluntary frisson', normally an autonomic response. Makes music a real.trip.
I can voluntarily open my eustachian tubes and hold them open, without needing to yawn or swallow. Makes it much easier to clear the pressure in my ears when changing elevation (like when flying in a plane).
I can hammer nails and icepicks into my head. I'm very fire resistant and eat fire. I have a split tongue. I can keep my eyes open for a VERY long time.
TBF I'm a sideshow and fire performer so I'm cheating
I can whistle from my throat, I figured out how to do it from yawning and just kept practicing, the wife hates it because it hurts her ears but every time I yawn I have a habit of trying
If I press on the corners of my eye it forces air down my naso-lacrimal duct (that lets tears drain into our sinuses) and it makes a squeak loud enough for people sitting next to be to hear. I have a built in nose flute.
I can whistle in three different ways. The classic pursed lip whistle, a whistle using just the tip of my tongue and the roof of my mouth, not using my lips at all, and then another using the tops of my bottom teeth. I can make decent bird sounds using my bottom teeth, but I can do pretty much any tune I can think of with the pursed lip method. It has been relevant to my life exactly zero times, except to entertain myself.
Sooo I can cause what honestly feels like a small and constant electrical current flow through any part of my body. If I center this feeling on my chest it is easily more prominent than anywhere else with my head being second. Extremities are dead last. If I am hooked up to a heart monitor I can make it freak out at will. Any location I focus it on tends to want to tense up.
I like to tell people this is the result of me grabbing onto a metal item when I was younger that was still hot. Couldn't let go for a solid 6-10 seconds, can't say exactly how long. What I am able to do feels very similar.
I can rotate one finger at one direction and the other on the opposite direction while pointing one to another, simultaneously. I don't know how uncommon it is but, back at high school, no one else in my class could do it. Totally unuseful skill.
I can put both my hands In a "pray" position behind my back between my shoulder blades. I can vibrate my eyes. Perpetually crack my right ankle. And pull my arm out of it's socket.
I can fit the majority of my little finger up my nostrils. My nose might be slightly larger than normal and my hands are about normal. It just fits up there with a little twist.
I can trigger a few seconds vertigo attack when I lie down. If I do not think about it when going to bed, everything is fine. But if I think about it, then it invariably comes.
I can spiral my tongue, so that the front part is fully upsidr down - but only to the left. I can't rotate it to the right at all for some reason, it's like the equivalent muscles are missing.
I can bring my hands from the back of my body to the front (and the opposite) while holding them together. There might be a use for this if I ever get tied up.
I can whistle with my lips just slightly open (like a ventriloquist).
I can make a really high pitched whistle like that and it confused the hell out of other people while they trying to find where the sound came from (high pitched sound is harder to pinpoint the location as it's bounce around the room).
But as I get older, I find it getting harder and harder to do so. 10 - 12 years ago I can whistle an entire song like that and it would sound crystal clear. Now it's really hard to follow a tune or make complex sounds.
I can fold my ears twice - so from the top of my ear I fold it towards the bottom of my ear and at the point where it folds I can fold it again across over the first fold.
Sometimes when I open my mouth really wide, I somehow spray a little stream of saliva, like from a squirt gun. It makes me feel like the dilophosaurus in Jurassic Park, but so far I haven't been able to do it on purpose.
Not a thing I can, but I once knew a person who could make their eyes go anti-crosseyed, as in left eye looking far left, right eye looking far right, away from their nose.
I can make my right arm vibrate by tensing up the muscles in my forearm.
I dont me shake really fast. I mean vibrate.like, fast.
Outside of beating my brothers on specific mario party mini games that require repeatedly pressing a single button (or other games that have that use mechanic) or unlocking the cheats in bomberman 64 (needed a turbo controller to hit start repeatedly on the main menu) its pretty damn useless.
There was one Mario Party mini game (i think called domination) where you had to hit A as fast as possible, with each press making a thwomp or "domino" appear in a line. At the end, they all fall down, and you see whose line is the longest.
Some people couldn't reach the finish line. Some could just about get past it. Mine just kept going and going.
We have a couple things that run in the family. All men in my direct family (so me, my dad and my brother) can twist our mouths in both directions at once, so upper lip one side lower lip the other side, looks funky. We can also do eyebrow dances with moving only single eyebrows but I think that's more common.
My left pinkie finger knuckle can hold some tension when I from my pinkie into a claw shape, but then snaps forward. Either that's unusual or my right hand can't do that as snappy.
I can snap the tendon over my knuckles kinda hard to where it makes a popping/snapping sound. If I do it close to someone's cheek, it stings like releasing a tiny rubber band.
I can also move my ears independent of one another.
I have a few that some others in the thread have already mentioned, but I can also:
wiggle most of my scalp back and forth
retract the middle of the tip of my tongue so when I stick it out, it looks like an ass
stop peeing mid-stream. Maybe this is perfectly common, but people talk about not being able to just stop, or at least not for longer than a few seconds.
I can make my left scapula pop/click by moving my scapulas closer together. I read on a medical website that it’s actually an ailment that can be remedied by surgery. I don’t really want surgery. I’m right handed, so it doesn’t affect me too much. Apparently, I’m the only one in my family with this issue and it’s supposedly a genetic issue.
