How the chart works
Each square is one week. A row is one year of your age, 52 weeks across, from birth at the top to 100 at the bottom. Grey squares are weeks you have lived, and the amber square is this week.
Most life-in-weeks charts stop at a fixed age, often 90, as if everyone lived exactly that long. Lifespans spread out far more than that, so here the weeks ahead fade with the share of people your age who live to see them, from the CDC's 2024 life table. Solid green weeks are ones nearly everyone your age reaches; pale ones only a few do. The dashed lines mark your average and the age half of people your age live past.
Why count your life in weeks?
Tim Urban's 2014 Wait But Why post "Your Life in Weeks" drew a 90-year life as a single page of squares, and Oliver Burkeman's book Four Thousand Weeks (2021) took its title from the length of an average life: about 4,000 weeks. Seeing the whole span at once makes it easier to choose what to do with the weeks you have, which is the point, not the number at the end.

Is this accurate?
The averages come straight from the CDC's 2024 US life tables. They describe a large group, not you: about half of people live longer than the average, and health, habits and income move the odds. Treat it as a picture, not a forecast.
