Let's make this birthday one to remember.

70 years old (Born on November 05, 1954)

Happy Birthday, Jeffrey Sachs! May your day be filled with more joy than an economist discovering a perfectly balanced budget. You've tackled poverty in "The End of Poverty," championed sustainability in "Common Wealth," and reminded us all about values beyond GDP growth in "The Price of Civilization." Clearly, you're the only professor who can make economics sound cooler than rock music.

Here's wishing you another year packed full of bestselling insights and groundbreaking ideas—because let's face it: if anyone knows how to turn complex global issues into page-turners (and still keep their sanity), it's definitely you. Cheers to many more years ahead!
