i can crawl through any space that my head can fit in (double jointed in several places)
i can fold myself into a wheel so that my head is touching my lower back, bend my shoulders in such a way that my torso width gets narrower than my head (limiting factor for moet ppl in fitting small spaces is the shoulders, i can fold them out of the way), and escape handcuffs and zip ties by movinf my thumb out of the way
i can't do all of these simultanoeusly tho
i won a few bets with these lil tricks
