Its just a meme or inside joke. People have said At fifteen, I had the will to learn ; at thirty, I could stand ; at forty, I had no doubts ; at fifty, I understood the heavenly Bidding ; at sixty, my ears were opened ; at seventy, I could do as my heart lusted without trespassing from the square. since before I even started playing the game, like a year ago
When people stop saying it then it probably will literally be dead.
Kind of makes it hard to have a genuine discussion about player number declining though, without people thinking its a joke
