Let's make this birthday one to remember.

86 years old (Born on June 04, 1938)

Happy Birthday, Don Catlin! You've spent decades chasing down performance-enhancing substances—talk about dedication. Thanks to you, athletes think twice before sneaking spinach smoothies or suspiciously speedy sneakers into competitions. Your groundbreaking work since the 1984 Olympics has kept sports fair and chemists busy.

Here's wishing a fantastic birthday to the scientist who made drug-testing cool (well, at least cooler than doping scandals). May your day be filled with laughter, cake that's definitely free of banned substances, and celebrations that pass every test imaginable. Cheers to another year ahead as legendary—and squeaky clean—as your remarkable career!
