Best:
- Old age whilst sleeping
- Drugged up
- Blown up by an unexpected bomb (that sounds real bad like Im promoting terrorism :S)
Worst:
- Buried alive
- Drowning/Suffocation
- In a fire with no escape so youre just stood there like hell no!
- Dying slowly of Aids/Cancer etc. when its just a waiting game
- Any form of torture where it drags out...
