44 years old (Born on May 05, 1980)
Happy Birthday, Hank Green! Another year older and still brilliantly explaining science while juggling guitars, TikTok trends, and existential crises. Your Brotherhood 2.0 videos with John remain timeless classics—proving sibling rivalry can indeed change the world (or at least YouTube). From your insightful Crash Course lessons to your hilarious yet oddly educational TikToks, you've made learning cool again.Here's hoping this birthday brings fewer awkward dance moves caught on camera—but let's be honest, those are our favorite parts anyway. Keep inspiring curiosity and laughter; after all these years of vlogging adventures with John, you're officially internet royalty now!
