It shows your age in units that feel more real than years: heartbeats, breaths, days alive, hours of sleep, and more. Enter your birth date for a personalized breakdown.
How are the estimates calculated?
Using average physiological rates (e.g., resting heart rate 70 bpm, 12–20 breaths per minute) multiplied by your exact age in seconds. Individual variation is not accounted for.
Does it need my personal health data?
No. Only your birth date is used. No health metrics are collected.
Is the tool useful for anything beyond curiosity?
Some people find it useful for perspective — understanding how much time has passed at the level of individual heartbeats can shift how you think about daily decisions.
