if you're not completely sick of hearing about terri schiavo yet, i highly recommend, rivka's two posts about the issue.
part one discusses the medical facts of the case, and part two discusses the ethical issues relating to it. both posts are excellent. she links to this post by hilzoy, which is also good. if you read rivka's exhaustive treatment of the issue and still can't get enough, make sure to read that too.
me? i'm getting pretty tired of it. but i am afraid it will be the top headline for a while still.
