Time Slips Faster with Age: Five Scientific Theories

Scientists outline several reasons why days feel shorter as we age: proportional theory (a year becomes a smaller share of life as experience piles up), novelty deficit (fewer new memories mark intervals), attention absorption during routine tasks, emotional flattening (burnout or monotony reduces distinctive memories), and dopamine changes that alter time processing. To slow the felt pace of time, experts suggest adding novelty—trying new activities, seeking surprises, sharing jokes, and pursuing new ideas—to create more memorable moments.
