so I'm watching an episode of South Park and go figure, I got curious. Kenny was hit by a bus and brought back to life however he was brain dead because it took over a day to revive him, lol. Anywho, the question came up in regards to does he have the right to die? Are people left on life support/feeding tubes/etc meant to stay alive until when? Their body naturally succumbs to its life span? Until a family member or spouse decides enough is enough? Or do they go on living forever?
