The Right to Die?

In class today we discussed do not resuscitate orders and death in general. The subject is hard to talk about because no one really likes to think about it. I think that personally there is such a thing as excessive measures to keep a person alive. Why would a person want to live as a vegetable for years when there is only an incredibly small chance that they will ever pull out of it. Then again, who can say for certain how they would react if they or someone they loved were in this situation?
