Lying in a bed for fifteen years, unable to move, and possibly in a lot of pain
Tiger, If this was proven to be the case then I doubt there would be so much media coverage and a humane way of helping her out of the pain would be considered.
However, whether she feels pain or not is an argument that doesnt work well for either those who want her dead or those who want her alive. Those who want her dead are arguing that she doesnt feel anything at all, thats why she should be allowed to die, she is a vegetable with no sense of feeling, no awareness of pain etc! Her brain doesnt respond to anything.
Those who want her alive say she has emotions, can feel, is aware, her eyes reflect the smile she has for her mother..
However, having these feelings would also mean that she can feel pain but cant disclose it, this would be awful. However she also smiles (which would indicate she is relatively at peace in her relationships). So the death sayers say her smile is just a reflex, she doesnt know she is smiling.
So the argument goes on...
