Happy birthday, Peter! Remember the math game “24”? It was cool way before the so-called hip TV show. Being 24 is nice, especially if you have younger relatives who are just learning multiplication, because (relative to other nearby ages) 24 is a multiple of lots of numbers. If I have cousins who are 8 or 12 (or 6 — I have smart cousins), I can win any argument by lording over them that I'm 3 or 2 (or 4) times as old as they are, so nyah nyah. And while they're scratching their heads trying to figure out what that has to do with anything, I can tickle their feet, undermining their ability to argue effectively.
