I am 20,000 days old today. I would never have known this but my very own mathematician (doesn't everyone have one?) informed me of this fact. If you try to do the math to see what that translates in to, please don't forget to add extra days due to leap years.
This grid shows what 20,000 looks like in dots. I love how sections of 10 x 10 dots in a 10 x 20 layout makes this grid pattern of 20,000 dots. A very construction fence-like grid!
