——— Terri Schiavo was not on any form of “life support.”-——
Except a feeding tube. Her brain was dead and would not permit body functions necessary to allow her to function and therefore to live.
Terri was not brain dead - had she been, there never would have been a controversy and no one would have heard of her.
If she could breathe on her own and her heart could beat on its own, then her brain was most certainly not "dead" by any medical definition. If her brain were "dead" then her bodily functions would shut down and she would die of whatever injury or malady caused her condition. Since her bodily functions did not shut down, she didn't die of whatever injury or malady caused her condition. Her cause of death was starvation and/or dehydration.
