American woman celebrates 116th birthday: secrets of longevity

Naomi Whitehead, the oldest living American, celebrated her 116th birthday, once again drawing scientists' attention to the phenomenon of extreme longevity. Research shows that genetics may determine up to 50% of the chances for a long life, and analysis of biomaterials from supercentenarians reveals unique biological markers.

On September 26, Naomi Whitehead, the oldest living American and the second oldest person on the planet, celebrated her 116th birthday. The event once again attracted the attention of the scientific community to the phenomenon of extreme longevity. Modern geneticists and gerontologists are trying to understand the mechanisms that allow certain individuals to surpass the century mark while maintaining mental clarity and vitality. Studies show that the influence of genetics on lifespan can reach 50%. Science gained the opportunity to study the anatomy of extreme age thanks to Maria Branyas Morera, who passed away in 2024 at the age of 117. Analysis revealed her strikingly young genome and the absence of chronic inflammation. However, heredity does not guarantee longevity for descendants: external factors and lifestyle can negate innate advantages.
