" But the decubitus ulcer presents a unique psychological horror. The word “decubitus” comes from the Latin decumbere, to lie down. As a rule, bedridden patients have to be moved every few hours, flipped like pancakes to ensure that the weight of their own bodies doesn’t press their bones into the tissue and skin, cutting off blood circulation. Without blood flow, tissue begins decay. The ulcers occur when a patient is left lying in bed for an extended period, as often happens in understaffed nursing homes. Without some movement, the patient will literally begin to decompose while he or she is still living, eaten alive by their own necrotic tissue. "
