Measurements, assumptions & sources +
Blink of an eye
A chosen 150 ms interval, not a universal blink duration.
Defined examples — our methodology
The marked time is calibrated. Unmeasured illustration details are representative.
Heartbeat
One beat per second corresponds to 60 beats per minute; this is a timing example.
