You don't understand that a phone isn't a part of the human body? Seriously? We as a society can't even come to agreement on that basic fact anymore?

If someone shoots a gun in a crowd is that too an involuntary bodily function? Is the gun not just part of their body? Are you confused by that as well? Where do we draw the limits on what is the human body? Who decides that? If I lay on the ground does the whole earth become my body?
