How we count: an average resting pulse of 80 beats per minute (60 to 100 is normal), 16 breaths per minute (12 to 20 is normal), Earth travels about 940 million km around the Sun per year (NASA), a lunar cycle lasts 29.53 days. People sleep about a third of their life. These are averages, your real numbers differ.
