Depends on the method for me - burning, for one, is a hard no. Hanging, probably not, too risky. But, I've considered other options - jumping, poisons, cutting an artery, drowning as a last resort.
Of course, like everyone I'd prefer peaceful. I don't want to be afraid, or to fail, or to be in agony. But I won't deny that there is a part of me that wants to truly feel my death. It will be my final act, after all, and I'm always sleepwalking through life. A small part of my brain is curious to see if I will finally 'wake up' upon facing my death. I know it's a foolish thing to even consider testing -since that's not how this works - so I haven't, but I can't deny my curiosity.
...This is all assuming I can get past my in indecisiveness and SI.
