Let's make this birthday one to remember.

67 years old (Born on November 05, 1957)

Happy Birthday, Daniel Todd Gilbert! May your day be filled with more joy than even you could forecast. Your groundbreaking research in affective forecasting alongside Timothy Wilson has taught us all that predicting happiness is tricky—but celebrating yours today? That's an easy prediction!

From enlightening Harvard lectures to the bestselling brilliance of "Stumbling on Happiness," you've shown us how humor and insight can beautifully coexist. Here's hoping this year brings fewer stumbles (unless they're into cake) and continued success as both psychologist extraordinaire and fiction-writing wizard. Cheers to another trip around the sun—may it surpass every expectation!
