I'm going to be a bit morbid here, but of all the diseases or mechanical ways to die, which would be your LAST CHOICE if given a preference. Dead last, so to speak.

Mine would probably be Rabies.
Radiation illness is one of them, there are certain yields that make it rather nasty. Rabies is also pretty high up the list.
Mechanically wise I remember the OSHA case of the worker getting trapped in a walk-in autoclave and literally steamed to death. because that actually takes a long time.
Prion diseases and locked-in-syndrome are also pure horror.
