How do people live beyond 110? Abundance of cancer-killing cells might be key

TL;DR - Research on people aged 110 and older examines how their immune systems continue adapting, with an abundance of cancer-killing cells proposed as one possible contributor to extreme longevity.

• The study focuses on supercentenarians, a rare population aged 110 or older.
• Findings indicate that their immune systems remain adaptive at exceptionally advanced ages.
• Elevated levels of cancer-killing immune cells might help explain their longevity.
• The limited item summary does not specify the immune-cell types, study size, or evidence for causality.
