I’m 26, no medical issues or mental health issues. I want an advanced directive with DNR, no feeding tubes, etc. In Nevada you have to have a terminal illness. Can I use a Medical Durable Power of Attorney for this issue? I wouldn’t want to appoint anyone to make these decisions, I would want it spelled out in black how to get prescription drugs without a prescription and white. Also, what’s a cheap but legally binding way of doing this? Thanks!
