Even if it's 25 seconds, you would still feel some pain. Anyways, another way i would die would be writing my last post on an AG Thread, that way armor games will be the last thing i did.
Cover myself in gasoline, with a long rope to ignite myself, and then hang myself with non-flammable material outside the window of a second-story building. That way, people see someone committing suicide and THEN getting engulfed by flames. Epic. Have I thought about this too much? :P
Sublimating would be stylish, but I guess it would be quite painful... Other than that, Seppuku. And maybe I can ask my relatives to vaporize my corpse after I'm done.
I'm a doctor in a hospital working when suddenly, a man walks in with a gun and starts shooting. Well, I hide behind a wall while everyone else runs away.
He comes running down the hallway where I'm hiding. WHAM! I punch him in the face and he goes down. I make a grab for the gun but am quickly pushed away because he is still conscious. We both make an attempt at grabbing the gun. We both are holding the handle when it goes off. Killing him and mortally wounding me. I die in a coma two weeks later.
