BornClock Longevity Leaderboard

How the Longevity Leaderboard works

The Longevity Leaderboard ranks members by their longevity score — the personalised life-expectancy estimate produced by the BornClock Life Expectancy Calculator. The score combines your age with self-reported lifestyle and health factors — sleep, exercise, stress, diet, BMI, smoking status and more — weighted using published population research from the WHO, the Global Burden of Disease study, and peer-reviewed longevity literature. A higher score reflects habits statistically associated with a longer, healthier life.

Scores are self-reported estimates, not medical measurements or predictions — the leaderboard is a friendly nudge toward healthier habits, not a diagnosis or a forecast of how long anyone will actually live. You choose a display name when you join, and only members who opt in appear here; you can leave at any time. To add your score, generate your forecast and join as a Premium member. Curious how the factors move a real number? Try the what-if simulator and watch each habit shift the estimate.
