I can speak to this one intimately. Your body informs your mind. You, as a worm, would not be the same person. You would not have the same thought processes. Simply dude to the physiological changes. We aren’t ghosts piloting around meat shells and the ghosts is where our consciousness lies. The meat shell is. Take away a major part of the meat and it literally affects how you think. Turn someone into a worm and they will think like a worm.
