ELI5: Explain Like I'm 5

Tempus fugit

"Tempus fugit" is a very fancy way of saying time flies. Think of time like a bird that flies really fast and never stops - that's what people mean when they say "tempus fugit". It reminds us that even though we have 24 hours in a day, time can feel like it goes by really quickly. So, it's important to appreciate and make the most of the time we have each day, because it won't last forever.
