Ask Lemmy

Can crack/pop most joints.

Can wiggle both ears individually or together.

I can cause my vision to go blurry on purpose - no idea if other people can?

I can hear some electronic devices that are plugged in, can also hear when certain portable devices have finished charging, so basically I have pretty good hearing.

I can pop my arms out of my shoulder joints, without using my hands, and back in again. Completely painless, but can sometimes do it by accident if I'm leaning against a doorframe etc, or pushing/pulling against something, so I have to be careful.

I can turn my face red by tensing my jaw.

I can turn my eyelids inside out.

I can forcibly go cross-eyed.

The back top of my skull is completely flat. If I shaved my hair off it would look like a chunk is missing haha. This also means there are dents in the middle top either side of my skull as well, almost like it has creased inwards. Was layed on my back too much as a child.

I have a seemingly hidden source of strength, I am very slim and not particularly muscular, but am stronger than some friends who are bigger and more muscular than me. I also find it difficult to add any visible muscle mass. Maybe I have dense muscle?

I can bend my toes back and make some touch the top of my feet.

• I don't get fevers. My immune system is above average, I don't have any diseases which affect my immune system, and nobody's sure why I don't get fevers.

• I have hyperphantasia, so when I imagine things, they look as real as real life, or like I'm watching a movie scene.

• I also have hyperthymia, which means I'm in a near continual state of mild mania (and I enjoy it!)

I can pop my neck at will thanks to a childhood judo injury. Thanks sensei!

I also have ridiculously sensitive hearing where I constantly pick up background noise, like a radio with its gain set too high. It's hard to hear people talk over the noise of a common house fan in the room.

I sneeze when the temperature changes significantly. I have no idea why.

I too get the hot ears. I always worry it's a tell in poker.

If I leave my stomach empty for too long, I can feel (and hear!) gas bubbles (?) coming up in my throat lining.

That's kind of crazy what happens with your ears with the pc monitor and all! Can you use over-ears headphones?

I think it's pretty wild that the body will just accept exogenous cross-sex hormones and start using them without issue.

EDIT: well, a caveat would be that cross-sex hormones would cause gender dysphoria for cis populations, and their brains don't function as well on them, but I meant more like even a cis person's body will grow boobs on estrogen or grow thick dark hair and develop stronger body odor on testosterone. It's just wild the body is so adaptable, though maybe it shouldn't be surprising since most people have all the hormones, just in varying amounts.

I can pop my ears whenever I want, like someone else mentioned. Handy on flights, but I haven't been able to teach my kids how. If I forget to blink for a bit and then blink involuntarily when my eyes itch, my jaw snaps shut also involuntarily, causing my teeth to snap together. I can roll my tongue, which is apparently a genetic thing. I can hear high frequency sounds, like bats, and rodent repellents. It can be painfully loud when noone else around me can hear them, so they have a degree of disbelief if I mention it.

Sneezing when I eat too much, typically 3 times.
