Well, you said it , "Keep alive."
...keep alive
The only alternative is...to Kill.
Kill...Murder...to unlawfully take a life.
Mercy killing... sounds so sweet, so good, almost like Pro-choice sounds to some people.
We all die.
Anyone who would keep me alive after 15 years of tube feeding, I would regard as an enemy.
Folks seem to think that if Terri had a cerebral cortex, she would be asking to live.
Personally, after 15 years, I would be begging to die.
