How about hypothermia? I've heard it's supposed to be a nice way to die, too. Too cold, though. I like warmth.
I want to be eaten by animals. Because, if you really are what you eat. Then it's like I "live on" in the animals and a part of me will be passed on to their offspring. Plus as a ghost I can be happy knowing that my corpse got something different then the normal stuff. Burned to ash,pointless. Rotting in the ground,a waste.
Souls cannot be owned, given away, or anything stupid like that. We are the soul, not the body. And I'm not the first to believe that the decay of the body is something to be avoided. Soooo why not give it to animals? It's just flesh, so I would choose to let some animal have another meal and keep itself healthy. I don't want children, so this is a way for my DNA to live on.
A sword fight is how I would want to go out. One big battle. I would want to die and be a part of something great, not for something. But out the choices I would pick being quartered along with hypothermia.
Actually, the lungs themselves do not burst. The tiny capillaries sometimes do from the exertion or struggle to hold one's breath while still moving, but the lungs themselves do not burst. Also, my father is a survivor of drowning. From what he describes, it's a very pleasant experience once your lungs force you to inhale the water. At that point, you cease to have the urge to breathe, the lack of oxygen causes the panic to subside, and you float in the water, with nothing but a peaceful feeling, and the notion that "Hey, this isn't so bad." in your mind; then you lose consciousness. In fact, my old man actually fought his rescuers when they grabbed him off the bottom of the pond he'd gone down in - the experience was that peaceful and desirable to him.
