I am hyper-mobile in every joint/socket above my waist, but with a possible exception of my knees (which I've never tested), none below my waist.
I can, however, stretch a foot and a half beyond my feet in the "sit-and-reach" flexibility tests at school. It freaked out everyone.
I am hypersensitive, mostly to light and sound, though I am occasionally known to develop mild fixations to some textures.
