According to a study published Monday in Psychological Bulletin, more than 83 percent of suicides take place when an individual is faced with the task of putting a fitted sheet onto a mattress. 'In the majority of these cases, people end their lives after trying in vain to get the short side of the sheet onto the long side of the bed, and at least one-third kill themselves after struggling with the final corner only to realize it is their own body weight preventing the sheet from stretching far enough,' said Johns Hopkins University psychologist Dr. Khalil Mazarhi, adding that suicide victims are usually discovered in close proximity to fitted sheets that are either partially covering a mattress or balled up in a corner of the room. 'The tragic irony of this phenomenon is that a significant number of people will actually use the sheet to hang themselves.' The study concludes with a recommendation that, for personal safety, fitted sheets only be handled when a second person is present.
