What about double jointedness? Here's a few things I can do;
-Bend my thumb RIGHT round the opposite way,
-Make my second, third and fourth fingers go crooked
-Bend my wrist forward so that the thumb of it touches the wrist with no gap beneath it
-Point my toes so far that they point a tiny bit backwards
- dislocate all my fingers, and my knees and shoulders
- make all the fingers on my hands bend up and back
- turn my knees sideways and up slightly
- make my mouth look like Wallace's out of Wallace and Gromit
- Go into full lotus position
Could this have anything to do with the connective tissue?
