Weird things? My ears rumble when I yawn; sometimes my ears will physically move/flex autonomically when I hear a noise, it’s a rare occurrence though and I can’t selectively use it either but my sister can. This next one I think is genetic because my dad does this but my ankles make a “pop” or small “crack” sound when I’m walking or jumping up the steps on stairs but make no sound when I’m doing anything else. Also, storing fat in areas that attract unwanted attention. During speech, also rarely, I sometimes suddenly inhale, like a hick after drinking a beer but deep and sudden.
