of course
But if the joint is already dm'd off, you can't hit the red part to dm it again (to my knowlege, although I could be wrong)
if the joints are in one piece, if you manage to squeeze the joints together somehow you can break the chest and the pec off without touching the pec. (though this would be extremely hard to do, like extremely. Extremely.)
Its like when you set your tori in the air at 300m, then set the grav to -1000.
your tori is will hit the ground with his feet, but the torso will still dm because of the pressure, and squeezing of the joints.
