Here's something to get started...
Presley Bishop came home from work depressed on 1st October 1978 in Littleton, Colorado, and went to bed. He stayed there for three years, during which he wore a hole in the bed, and lost 9 stone, and grew a beard down to his stomach and fingernails six inches long.
In August 1981 his widowed sister Bernice, in desparation, called the cops and he was moved to a nursing home. Asked by the police how he felt he replied: "fine". It was the first word he had uttered since he had taken to his bed.
