If I don't have a DNR, then I want CPR.
Seriously, but true. I think it's terrible that a peron doesn't receive CPR over a situation that one could easily be revived. If one is at the end of their life and have a DNR, that is something everyone needs to decide for themselves.
I think in cases where one needs extroadinary measures to keep one alive is another situation that someone needs to decide via a health care rider that expresses one's exact wishes.
