In ten years, medicine will think of our previous century as barbarism. PVS is voodoo science executed by Right To Die advocates like Dr. Cranford, Attorney Felos and Judge Greer. PVS, Lockdown State, and Minimal Consciousness are almost indestinguisable.
They are not synonymous with brain death.
If you like an intellectual argument I prefer on Terri:
If you believe she is brain dead and not experiencing anything, there is no harm in keeping her alive (except monetary).
If you believe that you don't know if she is brain dead and not experiencing anything, there is great harm in killing her, and NO downside for keeping her alive (except monetary).
We're growing neurons in petrie dishes today.
Five years from now, who knows?
Terri is gone, and no future cures apply. The money was there. Our will was not.
