How come they say Ned cannot touch anyone or they die, then how
come he can hug olive and even kiss her and she okay?
Ned's touch *only* affects the dead. The only effect it has on
the living is if the living thing in question is in random
proximity of the deceased that was touched, it will have to die if
the deceased is not touched again in one minute.
