Olivia Farnsworth has a rare chromosome 6 deletion causing her not to feel pain, hunger, or fatigue. She is the only known person with all three symptoms.

The claim that Olivia Farnsworth has a rare chromosome 6 deletion causing her not to feel pain, hunger, or fatigue is supported by multiple web sources, including high-reliability sources such as the Daily Mail. The specifics of the condition and its rarity are consistent across sources. However, there are no professional fact-checks found. The claim that she is the only known person with all three symptoms is also widely reported but primarily from medium-reliability sources. The lack of contradiction from any major medical journal or authoritative source regarding her unique condition adds weight to the claim's plausibility, even though the absence of professional fact-checks leaves some limitations in complete verification.
