I realize that Microsoft Excel’s sequential index for dates is, essentially, a record similar to my own recording of life-days, and thus, any time I wish to ponder the way the time we live in is segmented like a centipede by the circling of our planet around its axis every 5000 breaths or so, I need simply translate a date in Excel into that strange five digit number I have always found so inscrutable.
Today is, for instance, 42,688. I was born on day 30,124, which is about 150,620,000 breaths since January 1, 1900.
I have taken 63,000,000 breaths, give or take, and my heart has beat somewhere between 1,000,000,000 and 1,500,000,000 times.
There are 100,000,000,000 stars in the galaxy, and there are 100,000,000,000 humans who have ever lived, and that is the same as all the heartbeats of the entire lives of 33 men or women who lived to 100.
