Living on the island of St. Helena, the geriatric reptile has survived nearly two centuries of historical transformations and wars. Researchers investigating his extreme longevity discovered stable gene switches and youthful orderliness in promoters governing mitochondrial energy production. This genetic stability suggests that protecting gene regulation from entropy could offer valuable clues for understanding hum
