As I sit in my recliner pondering the speed of the earth around the sun which in turn is in rotation through the galaxy which in turn is speeding through the universe, I figure added all up I’m going about a million miles per hour which explains why I feel so tired at my age.
That speed is ~66,000 miles per hour (18 miles per second).
So if anyone nags you about sitting in your chair all day, "not going anywhere", show them this.
There are 3,600 seconds in an hour.
That's 18 x 3,600 MILES you've traveled every hour you were sitting on your butt!
