Let's make this birthday one to remember.

86 years old (Born on November 16, 1938)

Happy birthday, Robert Nozick! May your celebrations be as free and unregulated as the markets you've passionately defended. Your philosophical insights have inspired countless debates—mostly friendly ones—and sparked endless conversations about liberty (and occasionally who should pay for dinner).

Your groundbreaking work continues to resonate today; after all, nothing says timeless success like making economics students everywhere scratch their heads in confusion or nod vigorously in agreement. Here's hoping this year brings you even more intellectual triumphs—or at least fewer arguments over splitting restaurant bills.

Cheers to another trip around a freely orbiting sun!
