Grandparents cooking their way to immortality, one stir-fry at a time

An illustrated image showing two elderly people (a woman in red and a man in teal) cooking together at a kitchen counter. Both are wearing glasses and smiling contentedly while preparing food. The illustration has a warm, wholesome aesthetic with a beige background. The Nautilus logo and headline overlay the scene, suggesting this is a health/science article about nutrition and cognitive health.
