Co-sign. As long as it's painless and I don't feel anything and I'm not even awake, that's the 'ideal' form of death, if there is such a thing.I'm immortal until proven otherwise.
However, I'd like to die in my sleep, completely unaware that it was coming and feeling absolutely nothing.
I'd like to die while I'm sleeping. I don't care if it's because of old age, or because of drug overdose or anything like that. I just don't want to feel it. But I have no plans to die because I'm going to live forever.
