Eating yourself or 'Homo Autodigesticus' as it is called in medicine is a potentially lethal condition depending on where the patient starts. Which part of your body are you going to masticate first?
Yes. That would require creating a burr hole with a drill, followed by spooning out the cranial contents. Bleeding might be an issue and if you eat your motor strip early on, you won't be capable of any more spooning. Maybe start somewhere else?
Would I dissappear or would I become twice as large? Please explain.
