[syriacus]

"Disabled" means that you can't do some things, but you still have consciousness.

What about people with epilepsy or narcolepsy, who might be "unconscious" many times a day?

They are conscious when their episodes aren't occuring, aren't they?

Terri Schiavo will never wake up from her vegetative state. Her cerebral cortex is so degraded as to preclude consciousness.
