Let's make this birthday one to remember.

69 years old (Born on June 03, 1955)

Happy Birthday, Richard! May your day be filled with fewer mutations and more celebrations. Your groundbreaking work on nucleotide excision repair has certainly kept DNA strands everywhere breathing easier—talk about molecular-level heroics!

From your pioneering days at the Imperial Cancer Research Fund to unraveling the mysteries of DNA repair mechanisms, you've consistently shown that science can indeed have a sense of humor (especially when experiments decide to mutate unexpectedly). Here's hoping this year brings you as much joy and success as you've brought clarity into complex genetic puzzles.

Cheers to another trip around the sun without any replication errors!
