# Perspective

How many angels can dance on the head of a pin? Maybe you've heard that question. Have you given it any thought? One? One thousand? Infinity? Do you think it's a trick question....? The truth is unknowable, for obvious reasons.

But there are many questions of a numerical nature that are known. And you should know if you want to be a serious thinker and want to partake in serious conversations. The number that comes to my mind these days is the number of Americans (Americans, mind you, not citizens of the world) who have died from Covid-19, to date. According to the NY Times, that number is roughly 688,000.

Is that a big number? Relative to what, you should ask me. And that's the point.

It's a matter of perspective. How many hairs are there on your head? More or less than 688,000? How many miles from Earth is the moon? More or less than 688,000? How many cells are in the human body, or how many days does the average human live? More or less than 688,000? If you want to understand Covid and other big things, you should know. How many years ago did dinosaurs go extinct? How many miles is it to the moon? More or less than 688,000? Do you sleep that many hours in a lifetime? How many days do you, an average human live? More or less than 688,000? (Hint: MANY fewer!! Many.)

How many times do you blink a day (multiply that by the number of days you live and estimate that number!)? How many cells are in your body? How many people were killed by the biggest volcanic eruption in recorded history? How many miles is the circumference of the earth? How many words are there -- in common use -- in the English language? Which of these numbers is bigger or smaller than the others and by how much?

Which is the larger number -- the number of trees in the world or the number of thoughts in an average human's lifetime or the average estimated number of bricks in the Great Wall of China? The number of times you blink in a day or the number of cities, towns and villages in the U.S.?

When people throw big numbers at you, you should be prepared to understand them, especially relatively. Test yourself. Be humble. Be reasonable. Be ready and be prepared to be wrong.

And be kind -- to yourself and others. Because most of us are innumerate. We really don't get these big numbers. Also, please understand that 688,000 U.S. deaths in the last 18 months is a lot. A real lot.

Peace and love to you today and for the week ahead.
