Let's make this birthday one to remember.

64 years old (Born on April 15, 1961)

Happy Birthday, Carol Greider! May your telomeres stay forever young and your enzyme discoveries continue to defy aging. Ever since you uncovered the secret of telomerase back in 1984, you've been keeping chromosomes—and our admiration—intact.

Winning the Nobel Prize in 2009 was just another proof that you're ahead of your time (and perhaps secretly using some enzyme magic yourself). Here's wishing you endless happiness and laughter on this special day. After all, if anyone knows how to keep things timelessly youthful at a molecular level—it’s definitely you!

Cheers to many more years filled with groundbreaking science and joyful celebrations!
