I recently began my 500th week with my employer, during which time the stock price has risen from $40.00 to… uh, never mind.
Expanding that thought out a little bit:
- 500 months ago (1967) Bill Gates was just another twelve-year-old übernerd — he hadn’t yet been enrolled (bankrolled?) into the exclusive prep school where he got access to his first computer
- 500 years ago (1508) Michelangelo started working on the Sistine Chapel (cool!)
- 500 decades ago (specifically, on January 18, 3102 BCE) by the Hindu calendar, the Kali Yuga started. It’s a sort of “dark ages” in that tradition. Fortunately, they last “only” 432,000 years. I say “only” because that’s not long, compared to Brahman’s age of roughly 157 trillion (that’s 157,000,000,000,000) years.

More concretely, the earliest copies of the Epic of Gilgamesh — the oldest preserved story in human history — were only written in about 2000 BC, by which point the historical Gilgamesh had already been dead for five hundred years.
