Miguel Sanchez
(Unique injury) TBC
Not sure you understand just how painful sulfuric acid is, even if swallowed it's an immensely painful death. If you want a painless death get an oxygen tank for yourself, a vacuum pump and a serious amount of duct tape. Tape up all the windows and any air vents really well (you have to double cross tape the windows as well as the surrounds), put the oxygen tank on and start the vacuum pump with a setting for 510 hectopascals. At that pressure your blood is still a liquid but your body will slowly shut down while the pure oxygen keeps you alive but in a state of euphoria until you slowly pass out and your organs then start to fail.
A truly painless death.
