I hate this idea that our "self" is the brain and that every other part of your body could be thrown away and you'd still be you if you were just a brain in a jar.
The "self" is a hollistic interaction between all parts of your body. The brain is affect by your guts and digestive system, hormones released into hundreds of metres of bloody vessels, all resulting in different moods, thoughts and feelings at any given moment.
You change a part of the body and you change the effect that part of the body previously had upon the mind.
You can't just remove the mind from the body and expect it to magically function the same way it did before.
