How long will you live?
Answer twenty quick questions and see your projected lifespan — and your whole life laid out, one week at a time.
How it works
We start from the average life expectancy for your country and sex, then adjust it with two sets of questions: the real health factors that move the needle most — smoking, exercise, weight, drinking, diet, sleep, stress and relationships — and a dozen tongue-in-cheek modern-life habits, from doomscrolling in bed to leveraged crypto trading to back-to-back Zoom meetings. Add it all up and you land in one of five verdict tiers, from The Speedrunner to The Highlander. The "life in weeks" grid turns the number into something you can actually feel: every square is one week, and the gold ones are the weeks you still have. It's a reflection tool with a sense of humor, not a crystal ball.
Frequently asked questions
How long will I live?
Enter your age, sex and country and answer 20 quick lifestyle questions. Lifespan starts from the average life expectancy for your country and sex, then adjusts it for the habits that move the needle most and shows your projected age, the years you have left, and your whole life mapped out in weeks.
How is my life expectancy calculated?
We begin with population-average life expectancy for your country and sex, then apply research-based year adjustments across two sets of questions: eight real health factors (smoking, exercise, weight, drinking, diet, sleep, stress and relationships) and twelve tongue-in-cheek modern-life habits. The total lands you in one of five verdict tiers, from The Speedrunner to The Highlander.
Is this a real medical or actuarial prediction?
No. Lifespan is an estimate for reflection and entertainment, not medical or actuarial advice. Your real number depends on far more than a 20-question quiz — genetics, healthcare, income and luck all matter.
Is it free and private?
Yes. It is completely free with no sign-up, and every calculation runs entirely in your browser — nothing you enter is ever sent anywhere.
What is the "life in weeks" grid?
It turns your projected lifespan into a grid of squares, one per week. The grey squares are weeks you have already lived, the gold squares are weeks you are projected to have left, and the dark squares are beyond your projection. You can download it as an image.
