Let's make this birthday one to remember.

80 years old (Born on January 19, 1945)

Happy Birthday to the legendary David Courtney Marr! Your brilliant insights into computational neuroscience have left neurons firing in excitement and computers seeing clearer than ever. Thanks to you, we've finally figured out that vision isn't just about eyes—it's about algorithms, neural circuits, and occasionally squinting at confusing graphs.

Your groundbreaking work continues to inspire generations of scientists who proudly chase after the prestigious Marr Prize. Honestly, you've set the bar so high that even artificial intelligence is feeling a bit intimidated. Here's wishing you another year filled with clarity, laughter, and fewer blurry PowerPoint slides. Cheers to you!
