Cosmic Body Clock
Enter your birthdate and watch every biological counter tick live — heartbeats since birth, breaths taken, times blinked, years spent asleep, and exactly when today's memories will fade.
How many times has your heart beaten?
Enter your birth date to start a live biological clock counting every heartbeat, breath, and blink since the moment you arrived.
The Cosmic Body Clock turns your lifespan into a live dashboard of biological statistics. Every number updates every second — your heartbeat count, breath total, blink count, hair grown in metres, dead skin shed in kilograms, and the exact fraction of your life spent unconscious. The Ebbinghaus Forgetting Curve shows when today's memories will dissolve unless you review them.
How to Read Your Cosmic Body Clock
- Enter your date of birth. The clock initialises from the exact moment of your birth to the present second.
- Watch the counters tick. Heartbeats increment roughly every 0.83 seconds. Blinks tick every 3.75 seconds.
- Switch between Body Stats and Sleep & Memory to explore different biological dimensions of your lifespan.
- Check the Ebbinghaus panel to see exactly how long you have before today's experiences begin to fade.
Frequently Asked Questions
How accurate are the body counter calculations?
The numbers use population-average rates: 72 bpm resting heart rate, 15 breaths per minute, 16 blinks per minute, 15cm of scalp hair growth per year, approximately 4kg of skin shed per year. Individual variation exists — these are medically accepted averages.
What is the Ebbinghaus Forgetting Curve?
The Ebbinghaus curve, discovered by Hermann Ebbinghaus in 1885, shows how memories decay over time without reinforcement. Within 20 minutes you retain about 58% of new information. Within 24 hours, that drops to 33%. The curve shows you exactly how long you have before today's experiences become fragmented.
How is 'years spent asleep' calculated?
Using the population average of 8 hours of sleep per 24-hour day — exactly one third of your life. The REM paralysis figure represents the 22% of sleep time spent in REM (rapid eye movement) sleep, during which your voluntary muscles are temporarily paralysed.
Why do I have so many more dreams than I remember?
Research suggests the average person has 4–6 distinct dreams per night across multiple sleep cycles. Most are forgotten within minutes of waking unless a conscious effort is made to record them. The dreams counter reflects the total estimated dream count, not the remembered ones.
