Let's make this birthday one to remember.

81 years old (Born on February 23, 1944)

Happy Birthday, Ronald! May your day be filled with joy brighter than the toughest Mega Test question and laughter louder than those who attempted Titan without coffee. Your brilliant mind has challenged countless intellects worldwide—though rumor says even Einstein would have paused twice before tackling your puzzles.

Your legacy as a philosopher and creator of legendary intelligence tests continues to inspire curiosity, humility (and occasional frustration!) among geniuses everywhere. Here's wishing you another year full of clever insights, intellectual adventures—and perhaps finally crafting that one puzzle so tricky it stumps even yourself!

Cheers to many more brain-teasing birthdays ahead!
