Let's make this birthday one to remember.

92 years old (Born on March 23, 1933)

Happy Birthday, Dr. Philip Zimbardo! May your special day be filled with joy and laughter—just remember to keep the celebrations ethical; we wouldn't want another Stanford Prison Experiment on our hands! Your groundbreaking research taught us that even good people can behave badly under certain conditions, a lesson every parent of teenagers already knew.

In all seriousness though, your contributions have profoundly shaped psychology and continue inspiring generations of students worldwide. Here's hoping this birthday brings you situational happiness that's inherently positive—and free from any experimental mishaps. Cheers to many more years ahead filled with success (and fewer prison simulations)!
