Ooh! I have recently learned that I am "pathologically flexible"! Which is to say, I have waaaay more range of motion in nearly all my joints* than is normal and/or strictly healthy. (Which explains a lot.)
eta: probably related, my tongue is sort of ridiculously long. I can touch the underside of my chin or the tip of my nose very easily. And yes, I can open my jaw bizarrely wide, as well. Fits well with my love for eating? That's my story and I'm sticking to it.

*joints where mobility is limited by ligaments, that is. not things like the elbow that are limited by bones. also that my hamstrings are not overly flexible, so maybe people would say that doesn't count either, but in directions not limited by the hamstrings, my hips are still overly flexible! and excepting my thumbs, which are oddly limited. "to make up for all my other joints," I like to say.


Please to be expounding on this "smell the future" thought, smedds!
