I can whistle while either exhaling or inhaling
Idk how special or weird it is but everyone I’ve tried to teach the skill to seems entirely incapable of doing the inhale one
It’s super useful for whistling complex songs or long bits without stopping, though
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 sing really poorly.
I can blow air out of my tear duct. Really useful for clearing it out.
You know how you can end up with crusties in your eyes in the morning? Well that gunk comes partly from your tear ducts and drys there. So sometimes when I blow them out I get some light white mucus as well as tears. When it’s really full it will make tiny bubbles. Lol and it whistles a little so people in the same room can hear it.
Also as a party gag. Lol
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.
