Science facts involving the human body can be intriguing, fascinating, and even a bit disturbing. A 7-year-old girl named Olivia Farnsworth is the only known case of “Chromosome 6 Deletion.” She does not feel hunger, pain, or the need to sleep. In 2016, a car hit her and dragged her 100 feet. She felt no pain and emerged with only minor injuries. Living a life without pain sounds great, but a life without hunger or sleep? We love sleep as much as the next person, which is why we’re unsure how we’d feel having this disease. But Olivia doesn’t know any different, that is her normal. Other features involved in Chromosome 6 Deletion include developmental delay, intellectual disability, behavioral problems, and distinctive facial features, and can be inherited by a parent.
